Cursor randomly goes to screen corners

Strange behavior of my cursor! It frequently and without apparent cause goes to a random screen corner when I am using my mouse. I notice that it only happens when I have my hand on the mouse, but there's no particular movement that I can tell that triggers it.

I'm using the standard Apple wired keyboard and wired mouse that came with the iMac in the early 2006 Intel iMac 17" model. I'm running Snow Leopard 10.6.3, but this was a problem too when running 10.4.11.

It can happen in any application as far as I can tell. The cursor goes first to a screen border, then travels along the edge to the nearest corner where it stays until I move it back to where I was working. Lately it has been occurring more than once a minute when I'm using my mouse. It's driving me nuts! Please help!

iMac 17" (Intel Core Duo 2006), Mac OS X (10.6.3), 2GB RAM, 1.83GHz

Hi David

Check/clean the optical sensor on the bottom of the mouse with a Q-tip, it sounds like there maybe lint, dust or hair interfering with it. Then if that doesn't help try a different mouse surface or a solid colored matte finish mouse pad. Lastly test another mouse, most any optical USB mouse will work more or less the same as your MM.
