Recently, I've noticed that the Finder isn't running when I start up my iBook and log in. The little arrow indicator isn't under the Finder icon in the Dock, and when I click on the Finder icon, it pops up a message that says something like "Finder is not running". Strangely, the Finder does seem to be working, at least my idea of what the Finder is. I can open windows, move files around, etc. I can also bring up the Force Quit menu and Restart the Finder. After that everything looks OK. I tried Repair Permissions, thinking that might help, but this weird behavior still happens. Any ideas...? One idea I'm considering is reinstalling Jaguar from the original CD, but I'm wondering: (1) will my user files be erased and (2) can I install 10.2(.0) over 10.2.6?
