In Preferences I have Always Use Local Help checked.
In Registry I have UseOnlyOfflineHelp set to 1 and UserPaths > HelpFolder set to where my reference guide PDF is located. (I know it won't open it)
When I select Help > Documentation in CbB it goes directly to the website and automatically unchecks Always Use Local Help in Preferences.
If I'm offline, it warns me there's no internet.
Since there's no local help for CbB other than PDF, why are there options in Preferences and Registry?
EDIT: CakewalkHelp_Documentation_1.0.0.21.exe solves this issue.
