wx.StaticBitmap not working correctly with py2exe?

[Jay Camp]

I'm trying to package an application with py2exe.  However, on the
target machine (the one without python), my wx.StaticBitmap (which uses
a PNG image) comes out with a black background instead of being
transparent.

Is there an extra library that py2exe may not be picking up that's
needed?  I looked through the API but didn't see anything obvious.

Much thanks,

Jay
