Glossary text not appearing

We have a compiled HTML Help project that is having a major problem. Once the CHM file is compiled, it will open properly on the development machines with RH7 installed by double-clicking on the Help file. The CHM file opens on the contents section and contains a fully populated glossary tab.

However, something strange happens when this same CHM file is moved to the Help folder for the application. When the Help file is accessed using F1, the file opens on the correct page for the chosen function or on Search screen (instead of the contents) and the glossary tab appears empty. If the CHM file is opened directly from the Help folder, the glossary tab has terms and definitions.

HHActiveX.dll is indeed present and properly registered on my development machine. We recreated the same situation and results on another technical writer's machine (with a full RH7 setup) and on a programmer's computer (who had HHActiveX.dll properly registered).

Any suggestions would be most welcome.

Also, is there a 64-bit version of HHActiveX.dll?

Thanks.
