		  ASCENTIA 8XXN AND 9XXN DISPLAY DOES NOT WORK PROPERLY 
				  WHEN MULTITASKING WITH A DOS SHELL

PROBLEM

When using the DOS command  "mode bw80,50" in a DOS shell, under Windows, 
to switch the display to 50 column mode, there will be no line feeds in the 
displayed text if the user multitasks <Alt+Tab> out to Windows and then back 
to DOS shell.

CAUSE

The wrong version (ANSI.SYS) of the ANSI driver is loaded.

SOLUTION

Load Western Digital's WDANSI.SYS (to replace DOS's ANSI.SYS).

To install WDANSI.SYS, run INSTALL.EXE from the DOS video drivers disk, and 
select "utilities" from the drivers/installation screen.

Load the WDANSI.SYS driver in the CONFIG.SYS file (replacing ANSI.SYS).
