Z-Indexing Flash movies over other Flash.

Yo guys!

I'm about to start on a long route involving alot of fancy CSS Flash work. My goal is to have a layout that contains 3-4 Flash movies, some overlapping eachother so animations could potentially fly over another movie.

This works on my slick new computer... But has anyone encountered any issues with this, whether it be compatibility based, or performance base?

z-index seems pretty solid from what I've read. But using Wmode appears to be a little iffy, I know it flickers pretty bad on Mac Firefox when the browser is resized, but I can deal with that. Are there any other issues with Wmode I should know that could complicate things?

Thanks,
James

Updated: Turns out that when two Flash movies overlap, only the top one can receive clicks, rollovers, ect.

This is a major issue and I think Im gonna have to attempt my idea some other way.

Any tips would be appreciated!
