And I should have added:

(3) Show the code (unless it's 100s of lines).

If I had tried to run your code under Windows NT 4 with ruby 1.6.1 
(2000-10-05) [i386-cygwin], I would have encountered the following error 
first:

# ruby smart.rb
smart.rb:53:in `require': dlopen: Win32 error 126 - /Program 
Files/Ruby/lib/ruby
/site_ruby/1.6/i386-cygwin/gtk.so (LoadError)
        from smart.rb:53

This occurrs at the first executable code (i.e. require 'gtk'). Is this a 
version error due to a switch from Ruby 1.4 to Ruby 1.6? (I installed the 
Gimp, and put the /Program Files/Common Files/GNU dll directory on my 
PATH, so as to pick up the gtk, gdk, glib, and gdk_imlib *-1.3.dll's.)
