wxruby users - Aug 2004 - end_modal question

Really stupid question, but have you wrapped this all in an App class? If you
don''t have a
wxApp subclass driving your applications then all sorts of badness would happen.

Yep, It is: Below is my code thus far. I am a big fan of refactoring so 
it ain''t pretty yet!!

Here are my main classes: GameUI, Game, GameWriter, PlayLog and Play.

When a Game starts (is created) it starts the GameUI. The GameUI runs 
GameUI.start which prompts the user with the modal dialog. This is where 
my problem lies, in the ok_btn event handler.

-------------START CODE----------------
