Mouse moves randomly

My mouse cursor moves randomly around the screen, usually all the way across and almost always to one of the screen corners, in which I have hot corners enabled. I had this issue occasionally had this issue in Leopard, but now in Snow Leopard it's more common (maybe 5-10 times an hour). Any suggestions/solutions?

Issues rarely go away over time. This one is no exception. Can anyone help?

Hello m:

I suspect that is a mouse problem, although it is impossible to tell from here. I do not know of a setting or preference file that would cause that sort of behavior.

Like I said, I have had this problem in Leopard, though to a slightly lesser degree (in frequency of occurrence, not in how far the mouse pointer moves across the screen). I think 10.5.7 solved the problem though. It's probably a software issue. Can I "reset" the mouse and see if that does anything?

Hello m:

You could try resetting the PRAM:

Mine moves too, since the SL upgrade. I am watching it inch toward the bottom left of my screen right now. Once it gets there it invokes a hot corner. Unplugging the mouse doesn't stop the movement! This is one of the strangest bugs I've seen on a Mac.

I will try that. It might be some time before I get around to doing it though.

This happened to me only AFTER I reset the PRAM yesterday (due to an unrelated issue).

I just swapped mice with my Win 7 box.

I notice that sometimes in Boot Camp, and always with Parallels 4.0.xxx, both running Windows XP SP3, that the mouse does jerk, but the pointer seems to move away and then "snap" back to where it was, and it happens too fast for me to see if the pointer reacts normally while it's moving. Much as I don't like it, it looks like Microsoft has scored a meager point here. 🙂

THis also happens to me. It happened in Leopard and it happens in Snow Leopard. I had Apple replace the mouse and nothing. IT was less in Snow Leopard at first but now the mouse pointer appears all the way across the screen. It also makes the hot corners activate AND sometimes this happens right at boot causing the screen to light up then go dark until the mouse is clicked. IT happens on the WIndows side of the dual boot also (XPSP3). COuld this be related to the dual boot?
