Musings on QT7 wired bugs

Initially I thought all kinds of wired stuff was thoroughly messed up in QuickTime 7, especially in QuickTime Player 7, because my main LiveStage project was really broken. But after getting over the initial shock and doing a lot of testing, I am starting to narrow down the circumstances under which the bugs appear.

I have these wired QuickTime movies which have a skin and load child movies, so far nothing new. They all basically use the same LiveStage code, but the content differs.

Once opened in QuickTime Player 7, many things initially seem broken. (Depression sets in...)
- sometimes no response to mouse clicks in the parent and/or child movies, when mouseovers are fine
- Movie Info window sometimes shows invalid Current size, like -7 x -5 instead of 795 x 560, combined with movie itself displayed as all black
- Movie Info window doesn't always update to show the movie's information

BUT... here comes the interesting part... Try either one of these two tricks:
- bring another application to the front, then click back into QuickTime Player
- or... minimize the movie, then open its window again by clicking in the dock

Now the movie just works fine! All the bugs are gone! If the movie window was initially black, it now shows its image. When mouse clicks were first ignored, now they get a response. Content gets loaded OK. And if you hide, then reopen the Movie Info window, its information looks good too.

My conclusion: there must be something broken in the way QuickTime Player 7 _initially_ opens certain movies (skinned ones?), which causes all kinds of things to fail. However, after some kind of internal reset of QuickTime Player 7 (which you can provoke with a minimize/reopen or deactivate/activate), wired movies actually seem to behave completely normally.

Can anybody repeat this behavior? How about with your own wired & skinned movies? If this is fairly repeatable, it might be worth a bug report.
