When you're running it under Ruby 1.9.1 (which OS?), the buttons.rb program crashes on exit.

This happens also under Debian Squeeze running ruby 1.9.2-p180 and fxruby-1.6.20.
It seems that the destruction of the application is not working correctly, because
the following change - a bottom-up removal of all children before exiting - fixes

This is solved in 1.6.22.

FXRuby is a library for developing powerful and sophisticated cross-platform graphical user interfaces (GUIs) for your Ruby applications. It’s based on the FOX Toolkit, a popular open source C++ library developed by Jeroen van der Zijp. What that means for you as an application developer is that you’re able to write code in the Ruby programming language that you already know and love, while at the same time taking advantage of the performance and functionality of a featureful, highly optimized C++ toolkit.
