Hi Lee; glad to see you here at TheSwamp!
Do you know if Civial 3D 2011 uses a CHM file for its main help or Web Based Help?
Yes, Civil 3D 2011 still uses .CMH help files, located:
<InstallFolder>\Help\civil_2011.chm
All calls to a valid .CHM using HELP, SETFUNHELP, and ACET-HELP functions work fine... I am only experiencing the undesired behavior when attempting to direct the F1 to HTML & URL.
I will track down the Civil 3D 2011 install, and see what is happening.
I greatly appreciate your time and effort, Lee. :beer:
