DOCUMENT:Q160328 19-FEB-2002 [crossnet] TITLE :Internet Explorer 3.0 Causes Windows NT 4.0 to Blue Screen PRODUCT :Windows for Workgroups and Windows NT Networking Issues PROD/VER::3.0,4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server version 4.0 - Microsoft Internet Explorer version 3.0 for Windows NT 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Microsoft Internet Explorer 3.0 causes Windows NT 4.0 to BLUE screen when you quit Internet Explorer 3.0 while the Word 95 drawing toolbar is open. At the time of this article blue screen information was not yet available. CAUSE ===== Process objects were being destroyed on the destruction of the IE 3.0 process. IE 3.0 managed to have the last thread alive on the process which was being used for process object cleanup (which was a non-GUI thread). This thread handled menu cleanup but did not clean up GUI objects such as windows properly. The code has been changed to clean up process objects on Thread cleanup for the last GUI thread in a process. This ensures that a GUI thread exists for window cleanup for the menu notification window. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem has been corrected in the latest U.S. service pack for Windows NT version 4.0.
