PNG Transparency in Standalone EXE

Hi All:

I'm written a short program for use at work - both the target and development 
platform is WinXP and I have Python 2.4, wxPython 2.6.3.2 and PythonCard 
0.8.2 on the machine where I'm writing/testing the code.

The program has the company logo displayed on the UI in the form of a 
transparent PNG graphic in the bottom right corner of the panel. The logo 
displays perfectly when I run my code either from a DOS prompt or by a 
double-click on the .py file in explorer.

When I package the program up into an EXE, using standaloneBuilder, the 
resultant executable does not display the graphic correctly. It shows up with 
a black background instead of transparent. I get the same result regardless 
of whether I use pyInstaller or py2exe to do the conversion to EXE, which 
suggests to me that the problem may be due to the altered execution 
environment that is present when running a standalone application.

Problem is, I have absolutely no idea where to start looking to troubleshoot 
this - can anybody offer any suggestions to get me going? The only thing I 
was able to think of was explicitly setting the background colour on the 
Image component so it matched the colour of the panel, but this didn't make 
any difference.
