There's a few things in there that may confuse things. Dual-head is where one video board drives two screens, and that need not be the way the user has it, they may have two video boards. The system will know those two as screen 1 and 2 (assuming you don't have it set to either one virtual big monitor, or to clone). A projector doesn't have to occupy just one screen, it can be on both. The monitor known as 1 shows its rect in desktoprectlist[1], and 2 in [2]. If the monitor 2 is arranged to be to the left of 1, then you get the negative X numbers. A complication you'll hit when doing 3D is that OpenGL only works on one screen (not counting Matrox patches), and the one screen it uses will be the one that the stage mostly occupies. If the stage is across two monitors of the same size, OpenGL will be available on the monitor 1 (on a Mac it'll be the one with the menu bar). There are quite a few variations of how you could set up two screens, but the above is just to give you a feel for it all. -- [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).
