SYSTEM.INI Setting Needed for MS-DOS Box in Windows (99486)
This article was previously published under Q99486
SUMMARY
Sometimes when you are running Windows 3.1 in standard mode on top of LAN
Manager and you try to start an MS-DOS box, the screen switches to black,
then back to Windows, then displays this dialog box:
The Switch has been Prevented
Cannot Start Application
Exiting Windows and restarting can clear this problem, or you can fix it
by finding the NonWindowsApp header of your SYSTEM.INI and inserting the
following line:
TaskSwitchInt6f=OFF
