Well, my Panther install (or rather, simultaneous Archive Upgrade from 10.2.6 and transfer to a new G5) went nearly flawlessly. Except that mail is freaking out severely: It'll launch, and get mail, and all my old mail is there, but clicks seem to "miss"--a click will register well below or to the side of where I'm actually clicking, and the location changes randomly on every re-launch. Command-key commands also seem to fail, although the menus work. Every action is accompanied in the Console by a slew of "Invalid message sent to event NSEvent" errors. I've already tried repairing permissions, and I've also noticed that it works fine in a different user's account (also upgraded), leading me to believe that it's some sort of corrupt preference error. Anybody seen something like this before, or maybe have a suggestion for things to try and delete?
