Flash projector will not play as...

I'm hoping someone has some direction on this - I can't find
a word about it anywhere.



We have a projector that needs to play as full-screen, and
does on every computer we test it on... EXCEPT the Mac Mini Core 2
Duo that it is going to live on.



It runs correctly on every other CPU/processor combo we've
tried: G4 Powerbook, G5 Tower, Core Duo Mini and iMac. When we load
it on the Mini Core 2 Duo, though, it will only run in a window.



Any thoughts? I appreciate any direction someone can provide.



Thanks in advance!
