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

Problem

Symptoms: When the customer clears the screen, (F7, N, N), a one inch border displays around the screen that is a darker color than the screen, then the customer gets a dark box in the middle of the screen. These boxes will go away after the prompt at the bottom of the screen is gone. Also, the speed with WP 5.1 is very slow with this CGA monitor, the customer put a monochrome monitor on with a Hercules card and it sped the cursor movement up to 50% faster. The monochrome monitor also eliminated the squares. Solutions: This customer was able to bring three samples of the graphics cards that was being used to WPCorp for testing. Testing with the customers cards, it was determined that the problems reported are related to the scrolling routines in the video BIOS on the cards. This is a hardware limitation.
