Projector file runs super slow in fullscreen mode

I have created a flash application that runs crisp and smooth normally. However, when I set it to fullscreen using

fscommand("fullscreen", "true");

Then it runs slow as heck. My cpu usage shoots up to the 90%'s on all four cores. Strange thing is, however, that if I manually resize the projector chrome to take up the full screen size it runs smooth and crisp…

It’s not playing any videos or sounds, and there are minimal images. The swf file itself is 7 megs, and that’s almost entirely because I have to embed the chinese alphabet.

Anyone encountered this before? Know a solution?

Could it be from running dual monitors? It still only “fullscreens” to one monitor’s size, so I don’t think its’s twice the size without me noticing… I’m really not sure what’s causing it, but it gets suuuuuuuuuuuuuuuuuuuuuuuuuuuuper slow…

the swf and fla files are located at:

.fla is only 448kB, but the swf is 7megs.

Again, it runs fine when not in fullscreen, no matter how large I make the window, but if you play the swf file in flash player (i.e. not in browser) it will run slow until you press esc and exit fullscreen mode.

Any thoughtS?
