I switched from the Demo version to the Pro version (22.214.171.124) and uninstalled the Demo. Now when I access "Help -> Manual" and click on any item in the Index tab, I get this message:
The page could not be found
'file:///C:/Program Files/QCAD Professional Demo/doc/chapter19.html#3 points circle'
I have searched the Windows registry as well as the installation directory for clues but haven't figured out how to fix the problem (other than recreating the "QCAD Professional Demo/doc" directory and copying the help files into it).
