Hi I got a problem which I think is caused by Firefox/Facebook. Sometimes (quite often) when I'm in Facebook and scrolling down, suddenly Facebook starts to scroll on its own and then the cursor starts flickering. The only way to correct this is to restart the computer. Very often when i log in for the first time afters such a restart all my desktop icons are shown wide apart, and the I have to logoff/logon again. Then it works until the next time. I have switched the hardware acceleration of in Firefox with the same result. Acctually, it happend right now, and now I don't have Facebook open. If I can't fix it i have to stop using Firefox!
