I noticed that clicking on a blue slider bar inside a window and scrolling is painfully slow and staggered on a G3 400MHz, 384MB RAM, ATi Rage 128 video card, however, clicking on the window itself and moving the window very quickly is not a problem with no visible lagging / staggering. Moving the window even with animation in it (QuickTime movie) is very smooth with no lagging / staggering. What gives? Why does Mac OS X have such a problem scrolling and no problems moving windows? I can't believe Apple is purposely crippling the OS so we all will go out and purchase brand new G4's.
