In this case, what I am trying to accomplish is something along the
lines of how Keynote and Powerpoint behave. I only want to take over
one display, most likely connected up to a projector. But, I also
occasionally want to have it in a window. I'm not expecting any
controls to work -- this is strictly a view-only window.
Also -- the code currently works just fine for the case of a single
display machine or when the window is on the main display. I just
need to make it work when the window is on another display.
thanks!
