I looked at the log file and solved
my problem--turns out it sometimes takes more than one mouse click on the netbook before the program responds, and I really hadn't added my C93 charts
to the directory...
Still commissioning the boat, but have been succesfull with the charts
and the AIS
inputs. Did find a slight problem with the CM93 tide stations around Trinidad not showing up on Opencpn
, and reported that on sourceforge. Should be able to give the program a real workout soon when we get underway.
