Normally I would recommend posting to the wxPython list, but it's down
at the moment. Keep an eye on their website as I'm sure they'll let
the community know when it's back up.
In the meantime, I'd look at how the demo does the icon displaying. It
looks like they created the icon they use using the img2py script
which basically creates a python file representation of the image.
See main.py of the Demo, line 1129. img2py is in the following default
location:
C:\Python24\Lib\site-packages\wx-2.8-msw-unicode\wxPython\tools
Without seeing how you create the image, it's hard to troubleshoot,
but I would guess that you have an absolute path that you're using in
your script that is different than what the exe is looking for.
