Hi,
I'm using 10.1 on a G4 350 AGP with an Apple USB Keyboard(smaller iMac style one) and a Logitech USB Optical Wheel mouse. Every now and then when i move the mouse the pointer jumps to another spot on the screen. I use the mouse on my desktop although I've tried it on a black mouse pad and the same thing happens. I've also tried my roommate's Intellimouse Optical and it has the same results. My Logitech didn't misbehave at all when we connected it to his computer. Any ideas on what the problem could be? Is it software? Should I try another USB port on my computer? Thanks for any help.
