We just check [FxImage origin] and behave accordingly, and as far as I can recall that has always worked for us. But we do [[NSBundle mainBundle] bundleIdentifier] to distinguish real Motion from Motion effects in FCP X for other purposes.

I don't have a definitive workaround. 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. Darrin On Feb 2, 2012, at 9:38 PM, Garrick Meeker wrote: > Do you see any workaround in the meantime?

Do you see any workaround in the meantime? We didn't run into this until you fixed image checkout during parameterChanged (thanks!), maybe because our workaround for that happened to avoid any processing inside parameterChanged? Does this also fix the modal dialog hang?
