I couldn't do it clumpsier...:)

This is what I would do:

 f1 = File.expand_path(__FILE__)
 d1 = File.dirname(f1)
 d2 = File.dirname(d1)
 $: << d1
 $: << d2
 require "Classes/Window"
 require "Modules/InstanceCounter"

If you want to add more directories, upto the root, use this:

 entry = File.expand_path(__FILE__)
 while (not $:.include?(entry = File.dirname(entry)))
   $: << entry
 end
 require "Classes/Window"
 require "Modules/InstanceCounter"

(Just kidding...)

Just don't use "./" or "../" or any other "relative" references
to a file in a require statement. Trying setting up $:
correctly instead and feed require the name of the library
instead of filenames.
