According to reports, OSX 10.4 and 10.4.1 is freezing after ~2 hours of uptime when Watching QuickTime7 from Safari or Fullscreen / Using Slideshow / iPhoto slideshow “fullscreen” / ALL OpenGL games in Fullscreen, freezing in either entering or exiting the game.This happens with ALL 1.8 Ghz PowerMac G5’s (Late 2004 Model)! No fix for this bug unless Apple fixes it! Works perfectly in Panther.
Also a user reports that AppleCare has said that they are NOT fixing this problem, meanign THAT ALL 1.8 Ghz G5 PowerMac’s are zombie straight out of the box! Being unable to do any proper multimedia in fullscreen after 2 hours of uptime!
This is a serious flaw that requires public attention because Apple is selling the machines with TIGER without telling of this problem to customers of the new machine!
Also bug has been reported to ADC bugreport system, is still in Open status with many people (or duplicate).
