So I have a project that's 960x600 pixels and use a 24px playbar, so 960x624 total. This is the size that is displayed in IE9 on Win7 (and also with Google Chrome), but when I play the project in Firefox 4, the dimensions are 1048x680. What gives??? I was testing in FF and worried about my playbar getting cut off when I noticed that FF is scaling the swf up for some reason. Weird.
