It looks quite cool :-)  As soon as I have some time, I'll try it
out on windows.

This is a known problem. I think you can solve it by creating the frame with
a "visible := False" property, and setting it to true after setting the 
layout.

Can you send me the .png file?  I have never tried working with transparent
bitmaps and would like to investigate this. There is a good chance that 
I have
done something wrong in my abstractions so we should try some lowlevel
calls.

All the best,
 Daan Leijen.

ps. Have you looked at the latest direct pixel buffer functions in
WXCore.Image?  The lastest cvs version contains functions to
transform "Array Point Color" arrays into images and bitmaps
(but than you need to build wxHaskell yourself)

Thanks, this is nice to hear :-)
