I found a thread on Foxite where someone was encountering a similar issue. They apparently fixed the issue by NOT setting ON KEY LABEL. They write the following....

Actually, I must NOT set ON KEY F1. Then the control's HelpContextID calls the correct topic.

Waiting to hear if this does the trick.

>>Is this occurring when the program is installed on a network share? If that's the case it's probably a security measure in Windows. We've been using a kludge where our program will copy the CHM file to a local folder (e.g. local temporary folder), then set the help to the copy.
