Not having a real Windows CE machine, I cant confirm this. However, on the emulator, a PNG with an alpha mask isn't displayed properly - the mask is also plotted.
In addition, the mouse pointer doesn't related to the coordinates read by the program - could be another emulator problem...

Aw. I think I still use the built in functions to read PNG images from MS, which ignore the alpha channel. Please make the bitmaps 24 bit and use the pink colour as a cookie cut colour.
Yes, that works fine.
Any idea about the mouse position problem - is it an emulator problem ?
I fear it's my problem.
