Microsoft Win32s versions
1.1, 1.15, 1.2, 1.3, 1.30c
on Windows 3.1 exhibit no problems when using an S3 driver, with a resolution
of 1024x768 and 256 colors. However, the display is corrupted when Win32-based
applications, such as FreeCell, run on Win32s in the same configuration.
This is a known problem
with the S3 driver.
A general protection
(GP) fault occurs when the display driver is performing a bit-block transfer
(BitBlt). This happens whether or not Win32s is running. However, when
Win32s is not running, Windows recovers from the faults. When a Win32-based
application is running, Win32s catches all exceptions and transfers control
to the nearest try/except frame. As a result, the BitBlt is interrupted.
Certain S3 drivers
which exhibit these problems can be made to work with Win32s by making
the following edit to your SYSTEM.INI file before running any Win32-based
In the SYSTEM.INI
file, you will find an entry in the [display] section
Change this entry
Restart Windows and
the display problems will no longer occur.
If this does not
help, obtain the latest S3 drivers. It is reported that S3 driver version
1.3 does not have this problem.
