Subject: FXRuby simple FXTextField question

Hello,

  I've been learning to use FXRuby and it seems to be a to generate GUI apps.
  I'm having a small problem with an example I'm working on. What I want is a
  FXTextField that when I hit <return> its contents are then displayed in
  another textfield. The first part is easy using the TEXTFIELD_ENTER_ONLY
  flag on the first text field. The trouble that I'm having is when <return>
  is pressed the text is only displayed in the second textfield for a short
  time and the field then blanks itself.

  Below is the relevent snippit of code that I'm using. I have Ruby 1.6.7,
  FXRuby 1.0.10, and fox 1.0.11 installed. Also, the inputs.rb example
  supplied with FXRuby doesn't work correctly; you only see the output text of
  the command when you left-click and drag the mouse over the output window.

  I hope that someone can help me get over this hump!

  TIA, Matthew
