Thanks Tarun, I actually found alot of info on the problem in the bugs forum. Guess I should have looked alittle more before I posted. In some of the stuff I was reading it said they were working on a patch for this proplem with Firefox, do you know if thats out yet?
I just ran CCleaner and didn't look as close as I should have at the files it was going to delete before I selected to remove all. Now web pages look strange, I don't know much about the structure of a web pages but about all that I'm getting is very plain pages. The only part of it that I've ran so far is Cleaner/Applications/Analyze/Run Cleaner. Any suggestions? Will System Restore fix this? Many thanks
