MouseOver/MouseOut SLOOOW...?

Hi Adobe folks,

I'm just trying to do a basic rollover/rollout. I've used a varying frequency number and it doesn't seem to matter at all.

Does anybody know of an example of this that works? I must be missing something really basic as I can't seem to re-create it by coding it myself.

If anybody knows of any examples of this online I'd be grateful.

Thanks!
