Yes, absolutely, so what do you think I should do next?

Ahh - gotcha.

Sure that makes sense, and that would be fine with launchURL.

THANKS Glynn - YOU ROCK (as usual)!

The cause is from running it in the background in from a shell script. 
I removed the ampersand and everything is beautiful!

I will post a message on the Mac Wish list, now that I know what was 
causing the problem. As a temporary work around, I guess I can disable 
tcltkgrass from launching automatically and the user will just be 
required to start the GUI by pasting in 'tcltkgrass &'.

Thanks again,
