wxProgressDialog wonky under Win32

[Grant Edwards]

Under Win32, the bargraph in a wxProgressDialog hits "full"
about 10-20% of the way to the "max" value.  The attached
program illustrates this.  The "cacnel" button changes to
"close" at the correct point, it's just the bargraph that
doesn't work right.

It works fine under:
   RH7.2, Python 2.1.1, GTK 1.2.10, wxPython 2.3.2
Barphraph shows wonky behavior under:
   Win2K, Python 2.2, wxPython 2.3.2
   
Does anybody know how to get the bargraph to work right under
windows?
