Q135548: PIF Editor Reserve Shortcut Keys Settings May Be Ineffective

Article: Q135548
Product(s): Microsoft Windows NT
Version(s): 
Operating System(s): 
Keyword(s): 
Last Modified: 08-AUG-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Workstation version 3.51 
- Microsoft Windows NT Server version 3.51 
-------------------------------------------------------------------------------


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.

CAUSE
=====

NTVDM sets the reserved keys after switching to full screen mode, rather than
before switching to full screen mode.

RESOLUTION
==========

To correct this problem, install the latest U.S. Service Pack for Windows NT
version 3.51.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This
problem has been corrected in the latest U.S. Service Pack for Windows NT
version 3.51. For information on obtaining the Service Pack, query on the
