I am having a problem with a program under Windows and I hope someone out
there can help.  I have written a DOS program that uses BIOS call hex 10,
subfunction hex 11, to switch character sets in EGA graphics mode.  When
I try to run the program under Windows, the screen blinks off momentarily
during the character set change.  The program does >not< do this when
run under DOS.  How can I stop the blinking?  E-mail replies appreciated.
