I believe that some people may have had some success by using an NSTimer to delay changing certain parameters, though I haven't tried that myself. As for the dialog hang, that is also fixed in a future release. It's obvious GenArts got Edge to work - anyone have a clue how they did it? Darrin - can we at least get a 10.0.4 with this fixed by NAB? _______________________________________________ Do not post admin requests to the list. They will be ignored.

This email sent to site_archiver@lists.apple.com I tried using an NSTimer - but when it fires you're outside of the event handling code for the button that triggered the change, so even if you're inside an action block you can see each parameter updating in sequence - and it doesn't undo properly.
