SUMMARY
This article describes the reasons why you may be unable to switch from a non-Windows application in standard mode.

MORE INFORMATION
An inability to switch from a non-Windows application in standard mode can occur for any of the following reasons:


 * One or more of the Directly Modifies options is set in the PIF file for the application.
 * The application is trapping all keyboard input. The application must be closed to switch back to Windows.
 * The Prevent Program Switch option is selected in the PIF file for the application.
 * Shortcut keys normally used by Windows, such as ALT+TAB, are reserved for use by the application in the PIF file.
 * The wrong video mode is incorrectly selected in the PIF file.
 * Your video display is an EGA, and the driver EGA.COM is improperly installed in the AUTOEXEC.BAT file. Ensure that the file EGA.COM resides in the Windows system directory.
 * The non-Windows application is using a video mode that is not supported currently under Windows; therefore, Windows cannot save or restore the display when switching.
