The past few weeks I have been having a weird problem. I'll be typing along as usual, and suddenly the pointer will jump, sort of like this. (it actually happened while writing this).

actual: The how to geek................and so forth, but then suddenly:
forhowtogeek.lhe help me fix my problem........

sometimes (too many times) I won't even notice it until I've messed up a whole paragraph. Its like all of the sudden I'm typing in the middle of a previous sentence. Any idea of what it is?

I have a dell laptop, running it on its power cord to the wall.
2 partitions.
XP Pro (some time)
windows 7 most of the time.
I recently had to install sound and ethernet and modem drivers for the xp side (before I reinstalled everything on the same reformatted hd. .. They both work ok, except for this stupid problem. Any ideas?

Thank you. I'm using a usb port mouse. But that might be the problem, becuase just now, i touched it and the pointer started moving around in circles. You might have the answer. I'll let you know in a minute. Thanks Santo

Good to know it worked :)
