But maybe they can impliment screen dragging for at least screen with the same resolutions?
;-) That's what I was thinking. CyberGrafix allows some screen dragging even at different resolutions, though it's less than ideal.
:-( If the screen behind is a lower resolution, it appears in miniature at the upper left as it is revealed, with empty space to the right. If the rear screen is a higher resolution, the right hand side is lost off the edge of the screen. Sometimes the colors are all goofed up, as well.
:-) However, as long as the resolution is the same, it should be feasable.
