WordPerfect® 5.1 for DOS

Problem

Symptoms: When using Windows, each time a customer presses Ctrl-F1 to Shell to DOS and then returns to WordPerfect, the program runs extremely slow. WordPerfect rewrites to the screen one character at a time. It doesn't crash, but it is so slow, it is unusable. If the customer exits using the F7 key, it takes three minutes or more to exit by just pressing F7, N to save document, and Y to exit. Solutions: The problem is occurring because of expanded memory conflicts. This problem can be duplicated in-house if everything in the AUTOEXEC.BAT and CONFIG.SYS files is loaded into upper memory blocks. This can be corrected by increasing the EMS Required in the WordPerfect .PIF file to 600K and the EMS Limit to 1200K. The customer, on the other hand, was using HIMEM.SYS and making those changes to the .PIF file didn't help. When they added /NE to the Optional Parameters line in the .PIF file, it worked fine.
