I have this problem recently with my cursor jumping back to the middle of the paragraph when i type. (happened in yahoo mail and microsoft words) Colud it be a virus or something. I'm using AVG and it doesn't notify anything. I suspect tho that maybe it's a prank. Anybody is familiar with it? Many thanks in advance. p/s: i just installed patches from microsoft windows update, and realised it happened after installation. I'm running WinXP Home.
