I could see that this could just be an in-beta issue, but I am not seeing certain help files. I looked for another posting and didn't find anything related, so here goes...
From the design page I can bring up detail windows for Style, Mash, Carbonation and Fermentation. Each has a "Help" circle with a question mark in it at the lower left hand corner of the window. If you select this you get a pop-up stating "Message Could not locate help topic file: '/Applications/BeerSmith2.app/Contents/Resources/help/fermentation_profiles.html'", specifying the specific file name as appropriate for each window.
