Firefox scrolling disable flash

I have a flash menu built with actionscript with some tweening going on. I’m using a wmode=“Transparent” and when I scroll in Firefox quickly, it disables the menu. I have to click on it to re-activate it.

I read of this occurrence once on the Firefox board, the tester was able to fix his problem by adding another frame to his menu and triggering a loop.

I cannot due this due to the complex animation going on… anyone have an idea?
