Thanks for the confirmation. This method does indeed work without problems, 
and I guess it also will when I get to the 'pickle' part again...

With the new version I now know exactly what is being duplicating, so it 
won't be necessary this time, but it's certainly worth keeping in mind for 
the future. This experience made me realize that by including a reference to 
a wxWindows/Python object in mine, I actually had no idea what sort of things 
were being copied, or to what level. And maybe it's better that I didn't 
know... :-)
