Check the spring loaded pin that holds the door. I too mine off once to put the extra battery pack on and it didn't attach all the way.
This is my idea;
Seeing how I own the extra battery pack which uses the tripod/monopod screw in to attach to the camera it provides a steady and sturdy battery link. The way the door on the extra pack is hard to open so I doubt it's going to open itself or stay open "just a little". The door on the camera is flimbsy and is very loose even when tightly on. My suggestion: Invest in the extra battery pack. It's a great deal and only is about $100-140 without the extra battery (takes two normal battery's).
How did you get all the way over to CCR
