Problem

Symptoms: The customer's computer does not enter View document. When the customer presses Shift-F7, 6 (View Document), the Print menu stays on the screen with "Selection: 6" displaying at the bottom. Pressing F7 (Exit) takes WP back to the document screen. This only happens when using the Ahead VGA 1024x768 16 color display driver. The IBM VGA 640x480 display driver works fine. Solutions: The customer found (by booting the computer and watching the monitor) that the Ahead VGA card in the computer only had 256K video memory. With 256K video memory, the highest 16 color resolution that a graphics card can display is 800x600 (which requires 234.4K). The customer tried the Ahead 800x600 16 color driver and it worked fine. In order to display 1024x768 resolution at 16 colors, the graphics card must contain at least 384K video memory. The following chart shows the relationships between resolution, colors, and memory for graphics cards. Resolution Colors Memory Required ---------- ------ --------------- 640x480 16 150K 640x480 256 300K 800x600 16 234.4K 800x600 256 468.8K 800x600 32,768 878.9K 1024x768 16 384K 1024x768 256 768K 1024x768 32,768 1440K (1.4M) 1024x768 16,777,216 2304K (2.3M)
