Thanks for your report.

I cannot reproduce that problem here.
Can you please be more specific:
- Is there no menu for the reference manual?
- Is there a menu that does nothing?
- Is the help window coming up but empty or with an error message? What is the error message?

Thanks.

Please see attached, hope this will explain better than I can with words.

Can you please check if this hint in the FAQ fixes it:
http://www.qcad.org/en/qcad-documentation/faq#user_manual

This should happen automatically, but might not for permission reasons.
It's an annoying problem that keeps coming back and can't be fixed properly since the assistant is a 3rd party tool from Qt.

Yes thanks Andrew your suggestion has done the trick. Please mark this report as solved.

OK, thanks.
