Dithering Windows 9x BG

Hey, I know there's a way to do this but I've yet to figure it out... To "dither" the background behind a program like Windows 95/98/NT does when you're shutting down... in other words, how do I make that light gray tint happen when I want it to? Thanks for any answers.

Alright, if nobody knows that then how about how do I make my backgrounds totally transparent? As in, an open program will show graphics or whatever but where it would ussually be gray or a graphic it is transparent to whatever is behind it... I've seen this too and I know it can be done I'm just not sure how. Thanks again.

Why not checking out this nice Tip.. :-)

Thanks, you wouldn't happen to have any idea how to do the dithering stuff, would you? ;). Thanks for the transparent tip though, it'll help!
