Magic Mouse Cursor Jumping to Corners after Lion update?

I am also having this issue. No problems until I upgraded to Lion today.

The cursor jumps across displays (a cinema display hooked up to my MBP)

I am having the same issue on my mac mini (late 2009). Did not happen until I installed lion. Also seems only my mini via bluetooth.

I too have this issue.

Occasionaly, the cursor will jump to one of the corners of the display. I'm not sure exactly what prompts it jump, so I can't easliy reproduce it. But it does happen a lot.

It seems to jump when the mouse is not moving. Then, when I move it, it jumps to a corner.

Based on these few posts, it doesn't appear to be hardware specific.

I have a Mighty Mouse, which is obviously over BlutTooth.

I have a Mac Pro, with dual NVIDA 8800 display cards running three 23" displays.

This needs to get fixed, pretty quick.

I've already sent in a "bug" report.

I suggest everyone else does the same.

I don't know of this will help, but I had this problem in SL as well with the magic mouse till I installed this:

I've been using this ever since with all mice and trackpads...what's not to like, it's free.

magicprefs might help.

But I'd prefer that Apple address the issue.

Thanks.

I have the same problem after upgrading to Lion on my 27" iMac i7. I have both the wireless Magic Mouse and the wireless Trackpad. I have a 30" Apple Display that I work on primarily, and the cursor will jump over to the iMac Display lower right corner and trigger a hot corner (until I turned it off). Jumps for no reason.

I have tried turning some of the gesture settings on and off in System Prefences, but so far, nothing seems to work. The cursor continues to have a mind of it's own and keeps jumping to the hot corners. I've had to turn off most hot corners. This needs to get fixed.

Everyone, please send feedback to Apple so that this can get addressed in the next release.

Same problem here after lion.

Please post the issue here so Apple will address it.

I switched the wireless channel from the router to something else (was 1, switched it to 10) and seems to have resolved the problem with the wireless mouse. My cursor was all over the place before that.

Hope this helps.

Jesus Crist, this problem is so annoying, i did my part in the feedback page, hope they fix this fast.

I am going to try what vinteg said, ty for the help.

Take care.

Have the same problem on a 2010 Mac Pro since upgrading to Lion. Mine sporadically jumps to the lower right corner and triggers my screen saver. Is anyone else running Better Touch Tool? I'm running an older version....wonder if that's a common theme.

No, I'm not running Better Touch Tool, but have the problem of the cursor slamming into the lower right corner, although truthfully, the problem has seemed to diminish since the first day I upgraded to Lion on my iMac 27". Not sure why, perhaps the jump is from a combination of things when using the mouse, (a tap at the same time as a slide, etc.) Perhaps I am more sure handed with the mouse now.

Please report this issue to Apple, so that it will get addressed.
