Help! I've been having major problems with Panther. A couple weeks ago I tried to download OS updates and I also made changes to System Prefs. I think it's since then that all the trouble started. Now I get the spinning ball when I try to access System Prefs, Help Viewer, options in Disk Utility, Installer, etc. Also Safari does nothing. Also, one of my software apps. gives me an error message when I try opening any new files I created since these problems began. I've tried trashing preferences, running repairs with Disk utility, and a bunch of other stuff... nothing seems to work. Anyone out there have any advice??
