Thanks Stoney...seems the problem is actually within McAfee itself. The pc is virus/trojan/malware free...posting over at McAfee online forums [and chatting to others] this seems to be a problem a lot of people have or are having. McAfee has a component in it called QuickLite...seems if that's used it grabs the fonts key register and then flicks it out with anything else it finds. When ever we turn the pc off and then back on, the weird font reappears....have some instructions here of how to try and go about fixing the problem [which is a bit like dropping me in the middle of Siberia without a "How to Speak Basic Russian" book]...would be a lot easier if there were screenshots to go with the instructions [and I wasn't a chicken to have a go - scared of doing more damage] but it's gotta be better than having to open the network on the other pc, and then copy the fonts from one pc to the other every time we want to use the main pc. If all else fails, we will have to get the guy who fixed the pc last time to reinstall Windows XP Pro and see if that works. [he fixed it from a MAJOR crash earlier this year and kindly, and generously, put XP, McAfee Pro and the full Nero on...but didn't give us the discs...so, yeah...kinda a bit stuffed..but it could be worse...been there, done that...]

Think once this is sorted we might go back to using Vet antivirus stuff.

Cheers,
