              DESQVIEW AND AST SYSTEMS WITH BUILT-IN MOUSE PORT


PROBLEM:       AST systems lock-up when using DESQview, with a mouse
               connected to the mouse port.

AFFECTED
SYSTEM BOARD:  All system boards with integrated mouse port and the following
               part numbers:

               202273-001, 202343-001, 202343-003, 202351-002 202352-001,
               202360-001, 202373-001, 202377-001, 202385-001,

CAUSE:         Incompatibility between DESQview release 2.31, and AST's
               implementation of the mouse port.

SOLUTION:      A permanent solution will be the next release of DESQview.
               However, a temporary patch can be made by following the
               directions below.
