Hi, need help. All of a sudden my screen fonts have turned fuzzy. Not hugely so, but enough to make them a lot less than pin sharp. This is on a 24 inch Intel iMac, about 15 months old. If I boot and run the machine from an external firewire drive, the problem is fixed. But I want to use the machine as normal. This has nothing to do with the Universal Access system preference, and reinstalling the operating system from the system disks didn't help, either. It's driving me nuts. What has happened to my wonderfully crisp fonts? It doesn't matter what programme I use, the fonts all display slightly fatter and fuzzy. Yech! All help most gratefully received, you techies out there! Thanks Spudmaster general.
