Right. When surfing I occasionally get a small window come up titled 'diskserv'- 'This program has performed an illegai operation and will be shut down.' I click on 'Close', then nothing much happens.(I can carry on as normal). But sometimes the screen freezes for a minute thenwhen I use the scroll wheel on the mouse, it increases/reduces text size instead and if I try to type nothing happens-except vowels work with double dot above them (!?). Its happening right now- I'm typing this into notepad then copy/pasting it into message box. Any ideas?
