I've been having some weird problems with OS X. Safari always gives me a couple error dialogues when I start up, and now Mozilla quits at the moment it tries to render its first window. I've tried a lot of things, esp for the mozilla problem, but nothing seems to work. However, all the other users on my machine can use these apps without a hitch.
I'm thinking about backing up my Library directory and then deleting it - essentially I want to start with a clean user and then put all the important stuff back in - documents, preferences, address book, etc. I'd appreciate any pointers from people who have tried this, or suggestions of alternate solutions.
