Expanded Memory - Lockup While Printing
DocumentID: 652201

The information in this document applies to:
WordPerfect® 5.1 for DOS

Problem

Symptoms: A customer has 512K RAM with an additional 128K added to make 640K RAM plus his expanded memory (amount not known). When the customer tries to print from WordPerfect 5.1, PlanPerfect, or from his Library Shell, his keyboard will lock up.

This seems to occur at random, although it occurs quite frequently. The customer has tried using the /NE option and also the WPC=*,* command, but neither of the two commands has had any effect. It makes no difference whether he used the two startup options separately or together.

When his keyboard locks up, he goes back into WP. The problem cannot be duplicated. When he renames his backup file he does not get the option to rename .BK2, only .BK1 (even though he had two screens active during timed backup). His keyboard locks up only in WP products, as far as he can tell. Solutions: The customer tried the start options WP/NK/NH/NE all together and this seems to be working for him. This turns off expanded memory, to make sure his memory manager is not at fault. It also turns off any keyboard information and keeps WP from asking the BIOS for port information and printing to hardware port.
