Animation problems..


I have few problems trying to import my blender animation to unity, but that is not what I will talk about at the moment.

I made an animation with a hand & a gun with many meshes, each with a bone. The animation seems to be working but I mistakenly added a camera to the scene, and now when I remove it, I can’t select/edit my animation anymore from the dope sheet action editor…it just quickly switches to “new”.

Any ideas what I should do to remove it ?
O also is there an easy way to combine animations ? I have the gun & the arm animations separately.

Thanks for advance.
