Bob,

I have something REALLY odd happening when I try this.  I can FindWindowByLabel 
in one class, but it returns None in another class.  I copied the code from one 
to another so I know it is the same.  I have a single top-level frame (which is 
what I'm trying to get access to).  This seems like it would be so easy.  Any ideas?

Thanks in advance.
