PIF Editor Reserve Shortcut Keys Settings May Be Ineffective

SYMPTOMS

The Reserve Shortcut Keys options in the Advanced section of the PIF Editor are ineffective for ALT+TAB, ALT+ESC, and CTRL+ESC, if the PIF also specifies Full Screen Display Usage.

If an MS-DOS-based application is started in full screen mode using such a PIF, and the first keyboard input is one of the above combinations, a switch back to graphics mode is made, and the MS-DOS-based application appears as a minimized window, even if these shortcut key combinations have been reserved. If the MS-DOS-based application is subsequently restored to full screen mode, these shortcut keys are reserved as expected.
