Mac + FireFox + Q-time + dual screens = Weirdness

[limbo]

When using two monitors I get funny results with Q-time movies in FireFox on the mac

When I play them in the right window (secondary monitor) the movie opens, sans-chrome, in the left window? Odd.

I have only ever seen this in FireFox on mac, camino & safari work OK.

I wondered if anyone else gets this oddity & is there anything that can be done to stop it?
