Create new windows app.

Add HelpProvider.

Set HelpProvider HelpNamespace to C:\Help\MyHelpFile.CHM

Set HelpNavigator on Form to TopicId

Set HelpKeyword to help topic ID, e.g. 2

Run app.

Press F1.

Help gets displayed, showing the correct topic page as expected.

... then everything works as expected. However,if I modify the program to use a corresponding HTM file (built using RoboHelp), like this ...

Change the HelpProvider HelpNamespace to reference a corresponding HTM file, e.g. C:\Help\MyHelpFile.HTM

Rebuild app.

Run app.

Prtess F1.

Help gets displayed, BUT always displays the main index page. I am unable to get the help to display the correct topic page.

Should this work, or are HTM files not supported in this way?
