Subject: How to make TkLabel update immediately?

Hi,

I'm putting out some text in a window using a TkLabel. The problem is
that the text only seems to appear once the method has finished.
Is there a way to make labels update after .configure immediately?

Code example:
    btnExit = TkButton.new() do
      text "Exit"
      command {
        label.configure ("text" => 'Good bye!') #never appears!
        sleep 2
        exit
      }
    end

Thanks!
Ralf.

pm. Is there an "official" tk and/or gtk newsgroup?
