Why aren't we allowed to tell flash to process the UI event queue periodically in long executing subroutines?
Hell, just something to tell the client not to go into "Not Responding" would be more than enough. I call "validate now" periodically, but that doesn't help because I still get the "Not Responding" which makes it look like the software has crashed - a very awkward user experience. It seems like such a trivial thing for Adobe to add. Why don't they?
