"The display device is not currently set to support 256 colors. Please reset the display device and restart Windows!"
However, Windows Setup shows the 640x480x256 colors driver installed. What's wrong?
A This message is generated when the Has256ColorsPalette() routine in the
APPLICA_.C source file routine returns false. This can happen if the current
screen is not a palette-based device (e.g., it could be a vector device for
CAD/CAM users), or if the number of palette entries is not 256, or if all five
of the available device contexts are being used by other applications. It's
also possible the device driver being used is not setting the RC_PALLETE bit;
this can happen if the drivers are old (pre-Windows 3.0). Check with your
video-card manufacturer to make sure you have the most recent drivers.
