We have seen this happen, but not consistently, and as you say, only after you have been running it for a long time.
Just to be clear, this is happening when you quit (cmd-Q) and not just spontaneously locking up, right? I think we have already fixed the hang on quit, and if that's happening to you it's safe to just force quit and you won't lose anything.
But if it's the latter, a sample trace would help. When Catalyst is in this state, launch Terminal.app, and then type:
sample "Adobe Flash Catalyst" 10 2
(The quotes are important here.) A text file will be written out; grab it and post it here.

Hi Scott, yep spot on, its only when quitting or control+Q
