plz to halp?

So, I think I fucked up the other day. I was cleaning old programs off my computer, like you do, and there was this scroll program that I couldn't identify... so I uninstalled.

Only problem is now my computer's gone apeshit and all the scrolling is terrible as is the cursor and they just jump around on every page regardless of if I'm in IE or Mozilla. Uh, anybody know what I did and can tell me what I have to reinstall to make it stop?

I would be most grateful for the help.

Thanks.

(I have Windows XP on a laptop, just so you know this isn't a Mac issue).

ALL IS FIXED. I THINK. I'VE BEEN OUT DRINKING AND WILL NOT BE ABLE TO FIGURE OUT UNTIL TOMORROW.
