This happens on BOTH Mac AND PC versions of CS4.
I have a hand drawn animation of 2,050 frames. Nothing weird or special going on, some crossfades. No actionScript or anything.
Every time I try to export to QuickTime format, the progress bar goes along like you'd expect, taking around 3-4 minutes, and gets to 100%.
Then it just hangs. Forever.
The "Stop" (cancel) button does work, but no QT movie is ever spat out.
