Hi--

      I'm using Growl/Snarl[1] to post notifications from Squeak. Of 
course, they're somewhat annoying when Squeak is already the active host 
application. Is there some way to tell whether Squeak is in the 
foreground or background, as far as the host window system is concerned? 
  I only care about getting the user's attention when some other host 
application's GUI is active (and thus possibly obscuring Squeak's GUI).


       thanks!
