Magic Mouse Loses Connection

My Magic Mouse keeps losing its connection. Has any one else had this happen to them. I reapplied the update and had gone through the set again but the connection repeatedly is lost. Luckily I still have my wired mouse plugged in or my IMAC would be useless.

IMAC, Mac OS X (10.5.6)

Have/Had the same problem on BOTH my MacBook Pro 13 Retina and 15 Retina. Yes, loose batteries are an issue and yes, the many many suggestions in the thread help address that problem (I use the a double-thick business card stock between the batteries myself). What I also discovered was a BT SIGNAL/PROXIMITY problem.


I use a Henge Horizontal Dock for both machines and noticed intermittent connections/Jitter/Sticking when using the mouse a ~45 degree angle to the lower left corner of both MacBooks when the screen was down. Move the mouse to another angle, and all is well! To fix, I simply opened the screen. If I had to guess, the antenna for the BT is in the screen....get too close to the corner and at the wrong angle, and mouse response "jitters" and "sticks". Attached pictures show what I mean.


Hope this helps.
