WordPerfect® 5.1 for DOS

Problem

Symptoms: The customer has Quarterdeck expanded memory and it locks even with the 01/19/90 release date and using the /32 option. Every time the user is prompted with "Are Other Copies Of WP Running?" the system will still allow the user to go into WP. If the user exits right out and tries to go back into WP, it won't work. The /NE startup option will work. They are using version 4.23 of Quarterdeck. Solutions: There are two problems with the customer's DEVICE=QEMM parameters in the CONFIG.SYS:
1.      A VGA monitor uses the memory a000-afff for graphics and b800-bfff for text, so the user must NOT include=b800-bfff if they have a VGA monitor
2.      The expanded memory page frame CANNOT be placed at b000 because it will overlap the video memory. If, on the other hand, the user has only a monochrome monitor, they could specify INCLUDE=B800-BFFF and FRAME=A000.
