QEMM386: Exiting Windows 3.0 and Starting Word Reboots System

• Microsoft Windows operating system versions 3.0, 3.0a

SYMPTOMS

Quarterdeck's QEMM386 memory manager version 5.11 or earlier causes any program that uses expanded memory to reboot the system after you exit Microsoft Windows version 3.0. For example, if you start Microsoft Word for MS-DOS, version 5.0 or 5.5, immediately after you exit Windows, the system will reboot.

CAUSE

Quarterdeck Systems has confirmed this to be a problem with versions 5.11 and earlier of the QEMM386 driver.

WORKAROUND

You can avoid the problem by doing the following:

1. Start Word with the /x switch to disable Word's use of expanded memory.

2. Use the extended memory manager HIMEM.SYS included with Windows 3.0 (instead of QEMM386.SYS).

MORE INFORMATION

Quarterdeck corrected the problem in the QEMM386 memory manager version 5.12. A complementary upgrade to version 5.12 can be obtained from Quarterdeck's technical support.
