Works fine for me with wxRuby 1.9.9 on Windows, and I've been using 
ProgressDialog on OS X recently and not had any problems.

Are you in fact writing your own ProgressDialog subclass, and defining a 
method called 'refresh' in it? wxRuby calls 'refresh' upon Windows (with 
two arguments) when they need to be redrawn. This allows for custom 
handling in Ruby, but it will cause problems if you have a method with 
the same name that does something different.
