Magic Mouse's cursor doesn't move (but clicking works)
Two of my magic mice suddenly don't work anymore: the cursor does not move but left and right clicking and scrolling work.
I tested both of them with new batteries both on my MacPro and MBP.
A third MM (newest) works fine; so I must assume that the others (>1 year old) have a hardware malfunction which leads me to the question if I should buy a new MM or choose another product.
Does anyone have similar problems; what other cordless mice would you recommend?
MacPro 5,1, Mac OS X (10.6.8)
