WordPerfect® 5.1 for DOS

Problem

Symptoms: When the customer clears his screen, (F7-Save Document? No, Exit WP No), he gets a one inch border around his screen that is a darker color than the screen and then he 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. He is wondering if there is a problem with CGA monitors? Also the speed with WP51 is very slow with this CGA monitor, he 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 he was using 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.
