Update: I was playing around with Java to see if I could find the cause of the problem, and I crashed to a BSOD. I didn't get a chance to write down the whole file name as my computer restarted, but the problem was caused by a file called ''atidoeg3.dll'' or something like that. I take it this proves that the ATI drivers are the cause of the problem, and that we should contact ATI about it!
