Ah, gotcha.
Yeah, when I was digging around looking for some good code to use for the Region Window stuff, I saw examples of how to do the alpha transparency thing.
I didn't do it, though, because it only works easily on XP with the Dot Net development kit, and only on 2000 with some ugly hacking, and not at all on 95/98/NT.
However, if I can find an easy way to drop it in so that I don't have to code a lot of if/then special cases to compensate for the OS's that don't support it, then that might make a good way of indicating when the window isn't focused. I was thinking of taking the existing bitmap and just dimming it, but the transparency would work, too.
