Magic Mouse Sensitivity

At the risk of repetition and earning the wrath of forum members, I am repeating what I have read in various and sundry threads about Magic Mouse behavior and for which I have seen no hint of a solution. Maybe I missed it and I would readily accept a pointer.

My Magic Mouse installed and works fine with the exceptions noted here. I like the lack of the ball, which would require regular cleaning, and I find the normal scrolling via a swipe to be excellent. All works fine EXCEPT:

1) In Google maps the sensitivity makes it almost useless. Why it is so extremely sensitive in this application I do not know. The slightest swipe results in a stunning rocket-like zoom either in or out. The result is that one loses location and it is very hard to zero-in properly on the object of one's desire. Two things help: turning off Momentum-Scroll and reducing the Scrolling to the minimum. Even so it is hard to use maps efficiently, but it can be done. However, once outside of Google maps, the scrolling is hopelessly slow and needs to be adjusted back up. And - frankly - I think the momentum-scroll thing is fabulous!

2) When selecting lines of text or words in an editor it will suddenly leap a line or two up or down. I daresay this is my touching the surface and no doubt I will be told that I need to be more careful, but the fact is I have not had this problem with ANY other mouse - and I have used every mouse Apple has ever made - well, more or less - including non-apple meese. I take the greatest care to touch the surface directly, exactly and without any slithering, and if I am very slow, the jerking does not occur. But, again, for regular use the sensitivity is just way too high JUST at the moment of selection. Normally it is fine. It is as if it suddenly becomes very sensitive to the lightest of light touches.

Item above number 1) is a mystery to me. The Mighty Mouse had no problem and I presume the sensitivity of the ball remains constant across applications. So why does the sensitivity of the Magic Mouse surface seem to change? I can see how momentum would have a nasty effect in some instances, but even with this turned off it is very hard to use. And 2) is also causing me significant problems.

It seems that the rolling of one's fore-finger on the surface contributes significantly, and it is hard to eliminate completely. Perhaps if one has very thin fingers...

Any ideas? I have none...

I have exactly the same problem, and posted a note on Macintouch. You're the first person I've seen who also has a problem with Google maps and docs, as I do. I too have tried all the suggestions: changing preferences, being extra careful on clicks and scrolls, but the page just jumps regardless, and when I'm at the edge the work area simply slips out of frame. Very time wasting. Hoping for a fix soon.

I think there is more of a problem than I last thought and I have now resorted to using TWO mice! Both bluetooth, the magic AND the mighty mouse! Here is what I have figured out about the magic one:

1) The click surface is also the scroll surface. For me at least, when I bring my finger down to click it is almost impossible not to roll or slide just the teeniest bit, so the screen scrolls a line or so just before the click. With "momentum" this is exacerbated. So in Google maps, or Omnigraffle, the delicate selection and click is very, very hard. One must bring one's click-finger STRAIGHT-DOWN without any sideways or rolling motion. I find this quite hard.

2) I was messing with a program named MouseWizard, http://www.samuco.net/web/node/23, and I found that the mouse would sense my finger just about BEFORE it actually touched the surface of the mouse. In other words, the sensitivity of the mouse was such that even BEFORE I actually contacted the surface, the mouse would register my finger. As in 1 above, if there was ANY sideways or rolling motion the mouse would pick it up and the screen would move a bit. In Omnigraffle this was impossible, likewise Google maps in the zooming in and out it was terribly sensitive, even in Word it was sometimes hard to select a line or a word.

As I noted, changing "Scrolling" to minimum and removing "Momentum" helped, but not sufficiently, and besides - I love the momentum! Then when moving OUT of maps or Omnigraffle, or Photoshop too - any program where precise selection is required - I found the scrolling sensitivity was way too low.

None of this happens with the mighty mouse or a trackpad, so why with the magic mouse I wonder.

So I now have two meese, a magic and a mighty, and I am happy!

But I would like somehow to fix the magic mouse. First, there DOES need to be a sensitivity selection. This would measure how much "closeness" or "pressure" the finger needs to exercise on the surface for a movement to be registered. Then there is a clear, and "mysterious" in my opinion, sensitivity dichotomy between programs like Google Maps and a simple browser, the mouse is terribly sensitive in the one and fine in the other. Not so with the trackpad which would seem essentially similar.

If the mouse preference pane could be selected from the menu bar, like the "Displays" it might help a little. I could use one of them Macro Languages to assign key-strokes to selections like "Lower Scrolling" and "Raise Scrolling" and "disable momentum" and so on. But there is still a fundamental issue with the magic mouse.

So I shall use the Magic for general stuff and the Mighty for fine stuff and hope for a fix.

I do like it though, whatever folks say I find it very comfortable, easy to use and I do like not having a mechanical ball which I seemed to be forever cleaning!

Cheers - Lawrence

That would explain why in some applications the thing is uber-sensitive, and in others it is better. I still find myself rolling my finger ever so slightly when I go to click and as a result the selection moves just enough to cause me to bellow. And the fact that it senses my finger before it quite touches the surface - that causes problems too I think. The "touch" sensitivity needs to be adjustable, and Adobe will certainly need to listen to the settings.

It is a grand mouse, but more work is required. Do you think Apple is doing anything, anyway to get these thoughts heard by them I wonder?

I too suffer from this problem - google maps is a wild train ride and I never know where I'll wind up. Safari is another place where I have problems - a little too much twitch and I'm back on the previous web page. Sometimes a twitch in the opposite direction brings me back to my starting point, sometimes not. I suspect its related to the fact that the "back" command is at the top of the list in the contextual menu options. I agree with the need to have some sort of sensitivity selector.

For me it is not only Google Maps, Earth, Excel or the other applications mentioned here, it is also FileMaker, iPhoto and Aperture which are made by Apple. Handling is completely erratic, rendering this mouse totally useless. Worst piece of Apple hardware ever and I'm using Apple hardware since 1989. Fixed mine by throwing it against the wall and then into the bin. No magic in this piece of junk, I'm back to the MightyMouse.

First of all, I do love the Magic Mouse and have (mostly) learned to live with the issues. That said, I would love it SO much more if they could be fixed. As far as movement across the desktop - that's fine, however, it's WAY too sensitive. If I click on something, it usually double-clicks. If I barely touch the surface (usually accidentally) while in a program, it scrolls all the way up (or down) or zooms in (or out).

Here two temporary solutions:

1) software: applescript (that you can invoke with Fkey, using iKey software), which toggles swipe gesture on/off (substitute the word "Scorri" with the name of one finger swipe checkbox)

tell application "System Preferences" to activate
tell application "System Preferences" to reveal pane "Mouse"
tell application "System Events"
tell process "System Preferences"
click the checkbox "Scorri" of the first group of the window "Mouse"
end tell
end tell
tell application "System Preferences" to quit

2) "hardware" : a little sylicone disc (3 mm diameter, 1 mm or less height) glued (bi-adesive tape) on the surface of the magic mouse that creates a "swipe safe" zone, where I can click, beeing sure that no pan/zoom can occur.
