DOCUMENT:Q135548 08-AUG-2001 [winnt] TITLE :PIF Editor Reserve Shortcut Keys Settings May Be Ineffective PRODUCT :Microsoft Windows NT PROD/VER: OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- 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.
