Messages window jumping all over the place in Yosemite?

I'm experiencing the same issue. Very strange. I have also not been able to consistently reproduce it.

Same problem here - happens every time I give the window focus, then attempt to click on something.

One think I can reproduce reliably:

1. Switch to another application leaving the Messages window title bar (top bar with close/minimize/maximize buttons) visible.

2. Click to the Messages title bar (to bring Messages to the top)

3. Click anywhere on the screen.

You would expect the object clicked in step 3 to react, but instead the Messages window moves on the screen to the point where you clicked, so that the exactly by the point clicked in step 2.

Sorry, submitted by acident. The last sentence should have been:

Hi,

I have seen other Threads like this in the Yosemite > Messages sub section but I cannot reproduce it myself - even with your clear "instructions".

A rough straw poll of the different computers it has been reported suggests it is Laptops and Desktops that are effected and it does not seem to matter if a Retina Screen is present or not.

Do any other apps have this issue ?

What about FaceTime or the Game Center ?

This is also happening to me as well. Like clicking at the top of the window of messages, then click the entry box to type and it drops to the bottom. Or anywhere within the window. It kind of acts like it is centering itself to something.

Humm,

It seems strange it only effects one app.

However I am not surprised it does not effect browsers due to their ability to use tabs.

It is also odd that those that have the issue cannot resolve it by moving the .plist for Messages that holds the window info (com.apple.ichat.plist).

Window focus is normally handled by Quicktime and Quartz.

A review of these Search items may help.

Yes, this is exactly what happens to me almost every time I click on another window after using Messages, and it's driving me CRAZY because I use Messages all day long at work. Apple, please fix this glitch soon!

Hi,

Apple don't formally read these discussions

You need to give feedback http://www.apple.com/feedback/

Apple provides the "space" for the Communities.

It does employ a limited number of Hosts (Moderators)

More recently they have added "Community Specialists" who pick up on posts over 24 hours old (in theory) and post links to Apple Technical Knowledge Doc and help articles.

Level 6 Posters (and above) can post to a area in the Lounge called New Technical Issues.

Added to the Lounge area with a link to this Thread.

It seems that many are reporting that if the Main (chat and Interface) window is partially behind another app then clicking on it does bring it to the "front" but the next click to do anything moves the window to that spot on the Screen.

This seems to be something to do with the focus of the window.

The people I have asked and responded have said it effects new and older machine alike, including with and without Retina Displays.

Also Laptops and Desktop seem to be equally affected.

They also report that they have not found other apps that it happens to.

Asking people to delete com.apple.ichat.plist achieves nothing even though this .plist holds the windowing info.

At this point I am at a lost as to what to suggest and feel it might be beyond the scope of User to User Suggestions.

At the same time I also think the numbers are low.

I am having the same issue with Yosemite and MacBook Pro Retina. Happens every time as Cerha described above when you leave messages on the background and switch back to it by clicking on the title bar and then click anywhere else on the screen and the app will follow.

Needs Apple resolution.

EDIT

Now I have posted I can see gastonw26's post

I agree that this is probably going to need input from Apple.

I've finally been able to replicate the issue. It only happens when you click on the very top edge of the Messages window (when the sizing arrow appears). The next click you make will bring the window to that location on your desktop. Very annoying. I hope this helps and hope a fix is around the corner somewhere.

Hi,

I had it happen today trying to move a Terminal Window.

I seem to have the impression I was still dragging the mouse whilst trying to click and when I had picked up the window it followed the movement about.

However when I try to do it carefully to repeat it I can't replicate it.
