- TITLE :16-bit Windows-based Applications Keystroke Causes System Hang
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:buglist3.10
-
- ------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ------------------------------------------------------------------
-
- SUMMARY
- =======
-
- Windows NT may occasionally stop responding (hang) when the ALT+F4+F6
- keys are pressed simultaneously for a 16-bit Windows-based
- application. If these keys are pressed while the application is being
- loaded, a system failure may occur. A failure can also occur when you
- choose Save As from the File menu and press ALT+F4+F6 when new data
- has not been saved. Windows-based applications such as Microsoft Word
- for Windows, version 2.0a, and Microsoft Excel can also produce these
- failures. This problem is most common on keyboards that have the
- function keys located on the left side of the keyboard, in which case,
- the F4 and F6 keys may easily be pressed simultaneously by accident.
-
- CAUSE
- =====
-
- WOWEXEC produces a kernel-level failure through the Windows NT 32-bit
- subsystem.
-
- RESOLUTION
- ==========
-
- An updated WINSRV.DLL file corrects this problem (on Intel x86
- Microsoft Windows NT 3.1 installations). This file is available
- through Microsoft Electronic Services including CompuServe (WINNT
- forum Library2: Patches and Updates) and the Internet
- (GoWinNT.Microsoft.Com: AdvSys\winnt\unsup-ed\fixes\WinSrv\*.*). The
- file available on these services, WINSRV.EXE, is a self-extracting
- archive.
-
- To replace the WINSRV.DLL file, do the following:
-
- WARNING: If this file becomes corrupt when installed on NTFS, the
- system may fail to start. If possible, test this file on
- a FAT partition of a test system.
-
- 1. Rename WinNT\System32\WINSRV.DLL *.old.
-
- 2. Copy WINSRV.DLL WinNT\System32.
-
- 3. Shut down the system and then restart it.
-
- This replacement file is provided as is, and is not supported by
- Microsoft Product Support Services. A tested and supported copy of
- this file will be included in an updated Microsoft Windows NT Service
- Pack.
