Why do my wireless mice always stutter?
I'm on my sixth third-party wireless mouse, and they all seem to have the same problem. When I plug the wireless dongle into the back of my iMac, the cursor always seem to stick and stutter, and I can never get it to move smoothly and consistently across the screen. It's prone to sticking and then jumping to another area of the screen instantly. I used to think it was because the dongle was plugged into an expansion port, because once I plugged it directly into the iMac, the problems went away. But over the last couple of days, they've come back.
The mouse is a Logitech Performance MX, for what it's worth.
If anybody could give me any advice, I'd be very grateful.
iMac, Mac OS X (10.7)
