I've had my mac for a couple of months now but have had nothing but problems with fonts on it. I got some fonts from a designer I work with, but Microsoft office says half of them are corrupt and I should take them out. But when I look in Font book it doesn't have the fonts there. I don't know where the fonts are to delete off. I can't open any of the Office programs without it sorting through the fonts and rejecting them. I also have problems with the fonts in Quark Xpress. When I convert them using Acrobat Distiller it says the fonts are not available. I also have a problem at the moment with it going into sleep mode and disconnecting from the internet. I'll be in the middle of working and it'll just go to sleep and I'll have to start it again, but it'll carry on going back to sleep till I eventually manage to close everything down and reboot the computer. Final problem. A friend of mine has a problem with the Safari icon continously bouncing. She has tried everything to stop it, but no one can work out why it does it. If anyone can help with these problems it'll be gratefully received!
