Why can't a DOS program (that runs in VGA mode) be run in a window?

[Guest 98 Guy]

Is there a fundamental reason why a dos progam that switches the display

to 640 x 480 x 16 color VGA mode can't run in a resizable (or even fixed

size) window on either win-98 or XP? But instead it must run in

full-screen mode?

The DOS prog. expects to directly control the video hardware. The later

operating system can _sometimes_ _simulate_ a real system as far as the

DOS prog. is concerned, but not always.

 

Have you tried Alt-Enter to toggle between full-screen and windowed when

the DOS prog. is running?

 

(Do you have a particular DOS software in mind - if so, what?)

IME, right clicking will bring up properties where you can set

the window size, fonts, etc.

It may not work for ALL programs, depending on your OS and the

humidity in Redmond that day.
