Leopard won't remember default programs Everytime I restart/boot my mac and open up a mail application (thunderbird) or a web browser (firefox or chrome) I am always asked if I want to make it the default. This happens even if I click yes.

So, for some reason osx isn't remembering what I set as the default mail or web browser. I have already repaired disk permissions which didn't fix the problem.

Any ideas?
The problem was I was using the root user. Creating a new user sorted everything out!
