Malcolm,

One way to cheat is to edit the PNG and replace all white with off-white (RGB(255, 255, 254)). Then, set the transparent color (or area) to true white (if you can do that). Then, save the file as a BMP. You won't need a MSK file at all, since the true white will be what you want as transparent and the off-white will be what you want as white. No one will be able to tell that RGB(255, 255, 254) isn't true white by looking at it... ;) When I use bitmaps that contain any white in them, I always edit them and replace the white with the off-white. I never did like the idea of MSK files.

HTH,
Chad
