    			  BRAVO MS 4/100T HANGS IN OPTIMIZATION PROCESS

    PROBLEM

    QEMM 7.5 hangs when performing the (QEMM386.SYS) optimization process on the
    Bravo MS 4/100T system.

    CAUSE

    Quarterdeck's QEMM 7.5 (in which the QEMM386.SYS file is dated
    September 17,1994 or October 12, 1994) has trouble resizing XMS handles in
    the Bravo MS 4/100T system, a glitch that can interfere with XMS based disk
    caches (such as SMARTDRIVE) preventing the system from exiting and then
    reloading Microsoft Windows.

    SYSTEMS AFFECTED
    AST PART NUMBER AND DESCRIPTION

    All AST systems using QEMM 7.5.

    SOLUTION

    Quarterdeck has released a patch called QPAT2.EXE.  This patch is in a
    self-extracting archive file which is located on CompuServe, in the
    Quarterdeck Forum (go Quarterdeck).  For further information call Quarterdeck
    Technical Support at (310) 392-9701.
