Dear Monks,

I am creating a simple logon window with two Labels for the user name and password and two buttons for Login and Exit.

What I have been trying to do is to get the Login button to be pressed upon the user hitting the enter key after the password is typed in rather than them having to use the mouse to actually press the button.

The script itself works so far apart from this minor piece of formatting

Forgive this rather mundane question but I can't find the answer in the documentation.

Many thanks
