Interesting observation on black screen bug

[dikr]

While testing the mod I'm building I ran across those annoying black screens when looking at two levers. I only have this while aiming towards certain objects. Now, I have this actor in the cell who activates the levers with a couple of 'use item at' packages. (He opens a secret door for the player character). Whenever I kill him, the black screens while looking at the levers are gone. When he is alive it's there again. Could it be the way Oblivion handles script/package references on containers / activators which is the main cause of the black screen problem?
