MICROSOFT WINDOWS 3.0 AND ENHANCED VGA MODES
|
|
|
|
|
|
PROBLEM: When running the application WordPerfect 5.1 in 132x43 column
|
|
text mode under Windows 3.0 (Real, Standard, or Enhanced
|
|
modes) and switching between tasks using the <ALT> + <TAB> key
|
|
sequence, or using the Task List, when the user switches away
|
|
from and then back to the WordPerfect session the screen is
|
|
blank with only a flashing cursor on the screen.
|
|
|
|
CAUSE: Microsoft has advised AST that Windows does not support DOS
|
|
applications (WordPerfect and others) running in extended
|
|
graphics modes such as 132x43 column text mode or 640x400x256
|
|
graphics mode. Windows will only support standard VGA text
|
|
and graphics modes for these applications.
|
|
|
|
SOLUTION: Run DOS applications in standard VGA modes only.
