Firefox restarts Flash movie if enclosing DIV properties change

Question

I have a Flash movie embedded in some DIV. The trouble is that when I change any property of the enclosing DIV dynamically, Firefox (not other browsers) restarts/reinitializes Flash movie effectively resetting the whole progress (eg: file selection for upload, etc.).

Is there some sort of a workaround for this?

Answer 1

Try hiding it with visibility:hidden or if all else fails, position:absolute;left:-9999px.

I presume Firefox doesn't want to waste memory and CPU on Flash animation that's invisible, so it kills it.
