Hi,
Thanks for pointing that out. My application is 64 bit, though, as it
needs to handle fairly large datasets. Since the Carbon stuff is not
64 bit, I'm basically in trouble. Does anyone know of a way around
this? I guess an option would be to keep everything to the main
thread, but I'd like to be able to use the app while the movie is
being created. Any suggestions?
