It's been a while since I did real Win32 programming, but I seem to recall 
there were some indirect ways of determining if you had a Console 
environment, like calling GetConsoleTitle() and if it returns an error 
then you don't have a console.  Or maybe GetStdHandle() ?

If you detemine you don't have a Console, then create a pop-up dialog box 
showing the error with a dummy OK button?

I'd bet Corinna would have this kind of knowledge at her fingertips. :)
