Help! Flash crashes!

Ok, here’s the story, Mac just recently upgraded to Leopard. Flash now crashes when opening certain fla’s (that worked fine before). The files sometimes open, but then crash the app when I select something on the stage. In these cases I can actually edit the actionscripts.

I’m not sure if the crashes are related to Leopard; don’t remember if I tried opening one of the problem files since upgrading.

I’m on a MacBook Pro 17 2.33, 2gb ram. I repaired permissions (several times), ran various Onyx processes, zapped pram, removed all the prefs files I could find, and reinstalled the whole suite (CS3 Master suite). Bridge won’t even open; it crashes on opening.

Any ideas? I’d be willing to post one of the offending fla’s for somebody to see if there’s something obvious.
