Alright, so today I noticed that Mail was acting up. Each time I clicked on a new message to view it, Mail would quit unexpectedly. I didn't know why this was happening, so I went to disk utility to repair permissions. When I tried to do this, disk utility shut down unexpectedly as well. This is a new PowerBook, and it has been working perfectly since I got it in September. I did install a bunch of Widgets last night, including one that I made myself. Could this be causing my problems? Any advice?
