I have an issue with modal window, which is annoying me for last few days. I have an IBAction, in which my application starts execution of an asynchronous operation. This operation executes on a background thread and has callbacks which are invoked on that thread as well. In a callback I have to update my progress-bar, so I just invoke performSelectorOnMainThread: (as far as I know Cocoa UI is not thread safe). In the very last callback (which is also invoked via performSelectorOnMainThread) I need to notify user about successfull (or not) completion of that asynchronous operation via an NSAlert (and it must be modal). I call the NSRunAlertPanel function. And here is the problem - the window appears as it should be, but this window is extremely unstable, i.e. when I move the mouse cursor over this window, it disappears immediately! Pressing any key on the keyboard leads to the same result. Also, instead of performSelectorOnMainThread, I have tried messaging main thread with NSPort - same result.
Does anyone know what I am doing wrong? Any help will be appreciated.
