In our case there is one main window and a few other windows get 
opened one at a time (Platform.instance.createWindow with 
WindowFlag.Modal), increasing number of open windows to 2, and 
sometimes native dialogs are invoked in addition to the 2 DLangUI 
windows. I remember there was some glitches like if you press 
Enter in OS-native file dialog and it gets closed then an odd 
Enter key press message may be received by DLangUI window, but we 
used one simple trick: before opening some modal window change 
focus in current window to something harmless. After that 
everything worked quite well. But we're not using more than one 
active (i.e. not shadowed by a modal one) window at a time, so 
don't meet with issues you might meet there.
