If you use %, the size gets set to 500x375 and %'s get pushed into the html 
template.  I'd just set usePreloader=false and show your own mx:ProgressBar.

Subject: [flexcoders] Does the [SWF] meta tag really support widthPercect and 
heightPercent attribute?


link here http://www.actionscript.org/forums/showthread.php3?p=834470
seems to suggest that in addition to pixel width, I can specify
percent value (similar to how I do it in html flash wrapper). But I
can't get it to work. Is it really supported?

[SWF(widthPercent="100", heightPercent="100")]

Background:

The reason I need it is to force a nested swf's size to match its
parent container (loader?) width/height, so that the preloader is
shown centered with respect to the parent application.

Right now, while loading, the nested swf seems to be at a size of
500x325 (not sure where that value came from). And it is not center
aligned wrt the parent. And I end up with a preloader that is off center.

Any suggestions?
