Thanks all. Feia It was happening no matter what I used and on new scenes too. Xantor I have noooo idea how to update my graphics driver, but I'll look into that.My poor old puter may be beyond help in that area though lol. Khai yup it has today fixed itself. Tunsey sounds like you scared it straight with the threat of immenent death lol I'll have to try that next time. Last night I turned it off restarted it, turned it off cleaned all temp files ext and restarted again. Again and again it happened then today nothing it's absolutley fine. Next time maybe scaring it will save me some time ;) Appreciate the help all.
