SYMPTOMS
The Visual C++ Developer Studio may leave orphaned threads in memory after exit.

The Developer Studio disappears from the taskbar on Windows 95 or the task list on Windows NT, but the process sticks around with two threads, and it is visible from PView. Notice that the Developer Studio Debugger can attach to this process in a subsequent debug session.



RESOLUTION
The Developer Studio is orphaned in memory only when switching the books in the "Select Reference" dialog box after using the F1 key. To work around the problem, change the book selection from the Help menu by choosing Open Information Title before using the F1 key for online help.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.



Steps to Reproduce Problem

 * 1) Start the Visual C++ Developer Studio.
 * 2) Highlight a keyword in either a source file, a header file, or a help topic file that has entries in different information titles. For example, the word "printf" or "UNICODE" is in both the Visual C++ Books Online and the Microsoft Developer Library.
 * 3) Press F1 to bring up the "Select Reference" dialog.
 * 4) Switch to the other book in the combo box named "Titles which have index entries for :" and Display the topic.
 * 5) Exit the Developer Studio.
