When you are editing an HTML Help contents file with the Microsoft HTML Help Workshop, you may receive an access violation in Hhw.exe. This can occur when you are moving, adding, or deleting items through the graphical interface for editing individual items.

Also, when you are editing large content files, you can receive illegal operations error messages simular to the following:

HHW caused an invalid page fault in module HHA.DLL


HHW caused an invalid page fault in module MFC40.DLL


This is due to a bug in the HTML Help Workshop's memory management code.
