Whenever i right click on anything in the "my computer" window then exit the window my computer freezes. I am unable to click on anything and mush hit ctl alt del to get the task manager ( which still works fine) so i am able to restart without just turning the power off. I have reformatted my hd and am still having the problem. I'm running xp pro with service pack 1 on a dell dimension 4550 with the pentium 2.4ghz processor.
