OS2/3DS
Have you put a /BGEXEC parameter on the end of the Device=vsvga.sys line in
CONFIG.SYS? What video card/chipset/os2 driver are you using? My understanding
is that some vendor os/2 video drivers don't support background graphics.
FWIW, the latest Vibrant drivers includes a "null" driver – no graphics/no
background execution problem (for background slave rendering.)
