Funny, after I upgraded recently to 10.2.8 every so often the computer suddenly sleeps and doesn't wake up on my Beige G3. I had to reformat my HD for other reasons and the behavior still remained the same. By trial and error I discovered that if I launch Internet Explorer before anything else this wont happen at all. If i start with any other application this occurs after a while, If I start with safari the computer does this immediately.
Any possible explanation?
