                  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.
