I've been having problems moving through the menus on my Tour. I figured it was because I had been using the Storm for so long that I forgot how to use the trackball. (Not forgot... just rusty) Anyways, I was surfing through the internet when I came across article about the Tour's trackball being faulty on some devices. Now I've heard about the battery door and mine is tight as can be but I hadn't heard about this trackball issue.
Anyways... here's how to test:
Go to: Options>Status>And type in test
Once you've done that it should bring up a menu with a bunch of different test options. Select the keyboard and trackball options. Just skip the keyboard test and go to trackball. Once there scroll your ball as fast as u can in every direction. You should get numbers 4-6 (according to the article) if your getting numbers lower than 4, then your ball is defective. I've read where Verizon will just exchange the device for a new one in store. I don't know that for sure though, I am on my way there now. I'll post my results with Verizon after I return.
Hope this helps someone!
