Revision: 3.1.7
Release Date: April 17, 1995
==================================
1. Added support for 1024x768x256 colors, 640x480x64K colors and
640x480x16M colors.
2. Added support for the panning feature.
NOTES: - WINDOWS NT DRIVERS
1. In the 800x600 and 1024x768 resolutions, the screen image is
not displayed correctly on a CRT screen when the screen is
panned to the bottom of the display and the user switches
the display from LCD to CRT.
The Windows driver uses the Check_Cursor and Move_Cursor
routines to adjust the screen for panning. There is no
routine similar to Check_Cursor in Windows NT.
This limitation is caused by the absence of Check_Cursor
routine in Windows NT.
This problem is fixed as soon as the user touches the mouse
pointer.
2. When any of the selections in the "CURSORS" Applet from the
Control Panel is chosen, the cursor becomes a software
cursor and hence there is no panning.
This is a limitation of the software cursor in Windows NT.
