I'm running Panther on my iBook G3 500 MGHZ. Everything is pretty good except for some choppiness during screensavers and during transitions in i<ovie. They are very choppy and not smooth at all. iMovie is pretty much useless to me now because it's way too choppy (i didn't have this problem in jaguar). Also, iPhoto doesn't do the cross disolve transitions anymore. It simply cuts to the next picture. Does anybody know why it's performing this way on my iBook? I played around with displays in system preferences, but changing the monitor or number of colors didn't do anything for me. If anyone can help me out, I'd appreciate it.
