  Thanks for the response.
  This might work, but I am a bit confused as to how to pull it off. The edit window has the buttons and the new text. I am unsure how to use the button connected routine to update the main windows copy of the text. It seems like the child window will need to have access to the main windows variables, or the main window has to connect to the child window's buttons. Does the variable scope allow this?
  If this is the best route, than I can fuddle with it until I figure something out. It seems like there should be an easier way to do this. A lot of FX dialogs pass messages back to the main window, but these are all written in C. I haven't seen anyone construct a dialog strictly in FXRuby, but it seems like it should possible.
