I noticed last night that my game has a little visual artifact when running in windowed mode. It seems that the trasparency doesn''t work. I can see the transparent color instead of the background, but it works fine in exclusive mode. Any ideas? --------------------

How do you set the transparency color? Do you have a preset color, or do you read a color from the image?

The way I do it, is the first pixel in each image is the transparency color, and what I do is I lock the surface, and read this color value so I can set a source color key etc...

In windowed mode, what happened in my code, is the Lock() function was failing. This was corrected by adding the LOCK_WAIT flag, or by calling lock in a loop.

At the very least, try checking the the return value when you call SetColorKey.
