Use Logical Palette Switch

This item switches on or off the use of the logical palette of the just active video driver. This option is disabled if the video driver does not have a logical palette or if it is not large enough for use. The Splot program uses the logical palette primarily for the Pen Identification. If the Pen Identification cannot be used, the logical palette is used only for color resolution enhancement. Note that using the logical palette may influence another application that uses logical palette when it is not on top.
