This is seriously beginning to piss me off. At the moment, I'm running WinXP Pro, on a 1.01 gHz AMD Athlon, with 384 megs of RAM. But the problem started back before, when I was still using WinME. *shudders* Basically, this is what happens. I lose all control of my mouse for a period. Sometimes it lasts just a second, sometimes it goes for a few. (No more than thirty or so...). The mouse just basically freezes in place. Eventually, I'll get control of it back, and it'll do all the things that I did (move it, click on something) while waiting for it to unlock. But that's not the only thing it does. Occaisonally, as I'm rolling the mouse across the screen, it'll open up the shortcut (right-click) menu. I click to get rid of it, but it won't go away. I have to click on the menu, then click off to get it to go away. The mouse'll jump across the screen. I could be up at IE's back button, and it'll suddenly jump down to the System Tray. I'll be clicking on something, and suddenly it'll change...to *shrug* the scroll cursor, for example. But, by far, my "favorite thing" that it does, is it stops moving, or it'll start jumping ALL over the screen and right click...rapidly. Sometimes, it'll pull a combo, and right/left click. When it happens, I find myself being logged out of my ISP...conversations with friends closed...work lost. Like I said. It's pissing me off. I'm A+ certified, and have searched all of my textbooks, and asked many of my more knowledgeable friends. I've upgraded to XP, and that stopped it for a while. Then, I added another 256mb of RAM, and it went away for a while, but returned. I don't think it's the mouse, because I've swapped in another mouse, and it still did it. Does anybody have any suggestions short of taking a chainsaw to this thing?
