I have been trying to figure this out for just over a year now -[RESOLVED]-

Hi All

I need an expert whose seen this before:

I use an operation to create irregular cuts in a paint project that creates a mask using flood fill and blits to do an invert in a seperate picture box dc. I use point to get the current color and then feed it to transparentblit function which uses this to create the cut area and mask the outside edge of the cut when I move it. This works fine in Win 98. In XP I want to keep code downward compatable.
Here's the problem:
In XP the floodfilled color when inverted is recognized by point and when the dc is blitted to a form it still shows same number but for some reason transparentblit will not turn this color transparent anymore.
Does anyone know what I'm talking about? How can I fix this? Is it the floodfill or the invert on the original DC that's messing things up? Obviously something is either too fast or persisting where it didn't in 98. I've tried wait and doevent functions with no difference. Please, Please, Please help! I have been trying to figure this out for just over a year now.
