This leads us to service timers that apparently we weren't expecting to run until "later". Attaching a sheet and avoiding servicing the run loop inside -parameterChanged seems like a good workaround until we can address the issue.

I'll skip the window creation code but running it like this still hangs: [NSApp runModalForWindow: win]; as does this: [win center]; [win makeKeyAndOrderFront: win]; _shouldKeepRunning = true; NSRunLoop *theRL = [NSRunLoop currentRunLoop]; //while (_shouldKeepRunning && [theRL runMode:NSModalPanelRunLoopMode beforeDate:[NSDate distantFuture]]); while (_shouldKeepRunning && [theRL runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]); (I wasn't sure if I needed to add something for modal to work, but I would expect the default mode to work.) However, I realized that a work around is to just display this like a sheet (that is, use the current run loop implicitly). At the end of our plugin, check if a message is pending. If so: Create the window: NSWindow *win = [windowAPI createWindowWithContentRect:NSMakeRect(0, 0, 446, 244)]; NSButton *button = [[[NSButton alloc] initWithFrame:NSMakeRect(331, 12, 95, 32)] autorelease]; NSTextField *text = [[[NSTextField alloc] initWithFrame: NSMakeRect(24, 156, 402, 67)] autorelease]; // etc... Display: _dialog = win; [win center]; [win makeKeyAndOrderFront: win]; Exit from our plugin. When OK is clicked: [windowAPI destroyWindow: _dialog]; _dialog = NULL; This might be harder if you have existing UI code, so someone else might care about having this fixed. However, this method using FxWindowAPI makes our message dialog have the same look and feel. On Jan 18, 2012, at 10:30 AM, Darrin Cardani wrote: OK, thanks everyone for the additional information. We'll look into it. One option, which I haven't tried, may be to use the FxWindowAPI and run the current run loop in NSModalPanelRunLoopMode.

Thanks, Darrin On Jan 17, 2012, at 9:04 AM, Darrin Cardani wrote: Ganga, In the first case, you're probably getting a -parameterChanged: call on a thread other than the main thread in FCPX. If that's the case, you'll need to run your alert panel on the main thread, perhaps using [-NSObject performSelector:onMainThread:]. The timingAPI issue is a known bug that should be fixed in a future release. By the way, I saw your other questions. I'll try to get an answer for you this week. I've been on vacation for the last 3 weeks, so sorry for the slow response. Darrin On Jan 3, 2012, at 6:05 AM, ganga wrote: Hi all, I'm working on FxPlug filter for FCPX.
