The problem is that SVGA boards make the border be "color 0" in SuperVGA modes, and the Mac requires color 0 be _white_. Most DOS programs just leave color 0 black. The VGA "overscan" register, which controls border color, appears to work in "old-style" VGA modes, but not SVGA modes, and video drivers provide no standard way to set the border color. Blah! You get a black border without a VBE 2.0 video driver because Executor actually flips the pixel values when sending them to the SVGA screen! This imposes a small performance penalty, but is more visually pleasing. Sorry about this...I'm not sure how to fix it, unless we do a different hack for each video board out there. -Mat
