I can't help with your problem exactly, but this sounds like it is to do
with the Binding of the variable(s).
See the Pickaxe book: http://www.rubycentral.com/book/ext_tk.html

An excerpt:
"One small caution when using the code block form: the scope of
variables is not what you think it is. The block is actually evaluated
in the context of the widget's object, not the caller's. ..."
