hi, I am using a Vista PC. (boo Vista.) Sometimes CamStudio doesn't work; when I click on 'record', nothing happens. I can see the Hard Disk light of my PC flashing, so I think it is trying to create a temp work file. If I spend 2 days defragging my HD, sometimes it works. sometimes it doesn't. boo Vista. Does anybody else have the same problem, and is there a work-around? thanks
