SYMPTOMS

When you call the HTMLHelp function to open a specific Help file, a different Help file is displayed. For example, if you call HTMLHelp to open a Help file named HelpMe.chm, when you call HTMLHelp to open a Help file named Help.chm (while HelpMe.chm is still open), HelpMe.chm is displayed, and no error occurs.

CAUSE

This problem occurs when the name of Help file is derived from another Help file that is already open.

RESOLUTION

To work around this problem, name the application's Help files so that any combination of characters prepended to a Help file name do not collide with another Help file name.
