My G1 force closes my apps. How do I stop it from doing this?

[Wa da da dang]

My T Mobile G1 force closes Pandora, Facebook, the camera and even the home page on my phone. I don't want to reset the phone but I would like to use stuff without it shutting the apps off.
I have tried turning it off and on, removing apps and getting anti virus apps. What's the deal?

I know you don't want to do this, but the only way to fix this is to do a factory reset on your phone. If you don't want to lose any information, you can do a back-up with the app "Lookout Mobile Security". It's mainly an anti-virus security app, but it has a back-up feature, and when your done reseting your phone, you can re-download the app and use the restore feature to get your information you backed up.
