I noticed that, FCPX hangs most of the times if I call NSRunAlertPanel from parameterChanged method (some times it worked perfectly). Same code works in Motion 5 all the time. Does anyone know about this issue? I also noticed that timingAPI returns fps of motion template instead of current FCPX project. I am using timelineFpsNumeratorForEffect and timelineFpsDenominatorForEffect APIs. Is there any other way to get fps associated with FCPX project? Regards Gangaraju

Interesting - I've been able to successfully get the checkbox to turn off - it's the other parameter changes that will cause a hang. _______________________________________________ Do not post admin requests to the list.
