I've been working on a windowed environment for several days now. It's pretty cool and I've gotten almost everything working the way I want it to. It's entirely dynamic and loads a movie into the window content according to the name of the window movie clip clone. The only real issue is speed. The main slowdown seems to come from loading the movie into the window movie clip where it can be moved and scaled. You can take a look at what I have so far here: http://web.infoave.net/~akanathan/window10i.swf

I tried removing the alpha on the window background (they were orignally partially transparent). That didn't help a whole lot, so I tried making the movie used for content smaller - that seemed to make it even slower. If anyone could offer some suggestions on how to speed it up some, I would appreciate it.
