use only the first 8 colors (0 - 7), since the last 8 colors
(8 - 15) are reserved for font 2 table.  You may have to
set {font 2:Screen} table to the same VGA table as font 1 table to
see the color block next to the names.  Remember that colors 8 - 15
are for font 2 table, so there is no telling what it contains.

.topic ScreenDialog
 Screen dialog box 
  
The Screen dialog allows you to set various screen modes and select
which VGA font tables to use.  Windows 3.x and other OSs that allow
task switching may corrupt VGA font tables 2 - 7 during task
switches.  Only the two BIOS supported tables 0 and 1 are restored
correctly under Windows 3.1 with some VGA drivers.  You can
{save:SaveFile} your current configuration prior to task switching
and later {load:LoadFile} it if needed.

Use 640 X 400 to eliminate one pixel gaps caused by standard 720 X
400 VGA text mode.

Paging causes VGA screen page 0 to be copied between pages
1 and 2.  This help smooth movement and eliminate flicker.  If the
desk top becomes too sluggish then you may want to turn off
Paging.

8 color mode masks off the high bit of all attribute nibbles
forcing colors 8 - 15 the be the same as 0 - 7.  If 8 color mode is
turned off then all 16 colors can be used.
