Well, I can't tell you. I found these directives here: http://www.codeproject.com/useritems/flashcontrol.asp They are supposed to draw a "semitransparent translucent window" with a flash movie inside. But the code didn't compile with my compiler. I'm downloading VC++ ATM. > (I am not clear where UpdateLayeredWindow fits with GDI+ either -- > would I need to do this as a separate call in plain GDI?

Another article: http://www.codeproject.com/gdi/pxalphablend.asp recommends UpdateLayeredWindow again. Seems to be the right track. I don't know how that will go together with GDI+, though. BTW, another PNG-library is also mentioned in the article (paintlib). Mockey Attention: PowerPro's Web site has moved: http://www.ppro.org Yahoo!
