I'm trying to set the correct directory for CSDOCDIR in GUI CSDOCDIR and I don't find reference to this in the manual. When I place the the directory where a manual is located (the location I believe to be correct), ("C:/Program Files/Csound/doc/manual/) , I receive the following error: Manual file not found: "C:/Program Files/Csound/Doc/manual/.html" Seems like this would be a problem for most others, but my search only brought up questions with no answers. Since the filename is missing, this might be an internal or build problem? (BTW, selecting "Manual" from help returns nothing. Maybe this is another clue.) thanks, brad (Vista, Csound 5.08) -- Brad Fuller www.bradfuller.com
