OpenNetCF IImage and png alpha rendering

I have a simple project that displays a background image on a form,
then displays an image on top of that. Both images are png.

The second image contains alpha channel data to give a drop shadowed
look.

I'm using the OpenNetCF ImagingFactory and the IImage interface to
draw the second image to the form.

The form works and displays correctly when I deploy to the PPC
emulator, but when I deploy to my windows ce 5.0 device (not windows
mobile and not PPC) the portion of the image that contains the alpha
channel data is all black.

Both the emulator and the device have the same versions of the CF and
the SDF installed.

Does anybody have any ideas? Does the ImagingFactory depend upon
something in PPC that I don't have access to in my CE environment?

Thanks,
 
I wasn't aware it was a "feature" of the video device, but that makes
sense. I bet it's either not available or not enabled. I'll check.

Thanks for your help.
