My flat panel iMac's optical mouse pointer is behaving very erratically. It seems to have a mind of its own and jumps across the screen at inopportune moments.
Recent system changes: -folks at MacTown replaced the logic board (thanks!) -installed a 512 RAM memory upgrade chip -installed an AirPort card -upgraded from 10.2.8 (2nd edition) to Panther I seem to recall that the mouse was a little bit flakey before any of this happened, but it was very rare. Now it is happening often enough to be frustrating. Last night I looked at some Mac discussion forums, where people said there had been problems with USB devices (like mice) since 10.2.6. I have tried 2 different Logitech mice (both work fine on Windows computers) with no improvement. I also tried plugging the mouse into the other port on the other side of the keyboard. Plugging the mouse into a USB port on the back of the computer seemed to help temporarily but is not a permanent fix (also the cord is short and so are my arms!). Restarts with and without the mouse help for a short period of time. Any suggestions? Please?
