When a user or a program opens an HTML Help file by using a Universal Naming Code (UNC) path, all shortcuts in the Help file do not work.

The HTML Help shortcut feature was changed for security reasons starting with version 1.31. This change prevents shortcuts from working when the help file is accessed through a UNC path.

This change only affects shortcuts, and only when the shortcut is in a help file that is accessed through a UNC path. Users who access HTML help files through a mapped drive are not affected. Shortcuts in help files that are accessed through UNCs will not work correctly, and no error message is displayed unless an HTML file is specified for the Window parameter of the shortcut object. In this case, the specified HTML file is displayed.

This behavior is by design.

A UNC is a network share that is accessible by name. For example, if a user or program opens Alpha\Public\Myhelp.chm, then any shortcuts in Myhelp.chm will not open. If drive G, for example, is mapped to Alpha\public, then shortcuts in G:\Myhelp.chm work correctly.
