Well, none of the code I downloaded worked, I'm not sure why. But as I was fiddling around, I came across a Rectangle control in the toolbox - which handles transparency perfectly. Now, the redraw of these rectangles isn't as smooth as redrawing the graphics the way I was doing it, but I was able to place controls and use their mousehover/mouseleave/mouseclick events without having to 'track' where the mouse coordinates are. There's probably a way to get the EXACT x & y coordinates for such as system as I was using before, but for this particular program, I'm happy with the rectangles. Not as elegant, but IT WORKS - which is the main thing.
