Interesting. Some variation of this might suit me, but I think one other 
problem I'm having is that the ShowModal() method returns whenever a 
button is pressed, so even if OK is pressed with an empty string in the 
box, the dialog disappears and returns an "OK" value. I'll have to check 
in the wxpython group on how to handle this one, I think.
