Use Centerscreen wonkiness...
 

I consistently have this problem in dungeons with many doors:

I'm viewing the game using the 3rd camera mode (3rd person fixed)

For awhile, I can open doors etc. using "Use Centerscreen".

Somewhere in the process of pulling, it stops working, forcing me to use 1st person mode to interact with things w/o the mouse.

Has anyone else had this problem?
