Don't use package GUI.  The following code appears near the top of GUI.pm:

   # Reserves GUI in the main namespace for us (uhmmm...)
   *GUI:: = \%Win32::GUI::;

That will effectively move anything you define in the package GUI into 
the package Win32::GUI - which already has it's own exporter, so I'm not 
surprised you're seeing problems.

I've looked at it a number of times and would like to remove it, but I 
don't know it's history.  I assume it's there for historic backwards 
compatibility reasons, and that the package was originally just called 
'GUI' rather than 'Win32::GUI' - this line would have kept old code 
running - but I haven't been around long enough to be sure there isn't 
anything else that depends on this.

Does anyone know for sure?  Should we remove it?
