Unable to launch html helpfile
 

Using Excel XP.
Made a html (.chm) help file to be launched from a userform.
All went well when the helpfile had a single topic, but now that it has 3
topics I just can't launch it at all.
I tried to launch it with 4 different ways:

ActiveWorkbook.FollowHyperlink _
Address:= etc....

Shell ("c:\windows\hh.exe " & etc...

Application.Help etc....

I also tried it with API calls according to instructions from John
Walkenbach.

The .chm file opens fine when launced directly.

Any advice greatly appreciated.
