Thanks for all the answers.
cancelTracking did not work; whyever. I called it recursively for 
every NSMenu in the mainMenu. The hanging menu does not close.

The suggested performSelector:withObject:afterDelay:inModes: works 
perfectly; the opening of the dialog will be delayed until the menu 
closes. Thank you!

(The only problem is, that I have some cross-platform code that 
requests the platform specific GUI code to open the dialog and not 
return until that dialog closes. Now, by adding the performSelector, 
it's no longer synchronous. So I have to change the requirements of 
the cross-platform code to be also asynchronous with some callback 
once the dialog closes etc.; but it's no problem in this case.)
