Well, I create one plain window for each thread to be used w/ OpenGL  
rendering, that's legitimate. Using

	ProcessSerialNumber psn = {0, kCurrentProcess};	
	TransformProcessType( &psn, kProcessTransformToForegroundApplication );
	SetFrontProcess( &psn );

I was able to solve the background issue. I still have some problems  
wrt event handling because I want to own the application main loop,  
but I will get there...
