I've made a really dumb first-timer mistake. I don't know why the strip across the bottom of the
screen just appeared when trying to set up GPS, but the Long/latt displayed did NOT mean the GPS was working with OpenCPN. It displays the location of the cursor which just happened to be my at
current location. A foolish confusion on my part. I still have to continue working on connecting the GPS, but I did find out about the
Open CPN sub-forum [thanks Greg]. Some oood there. Sorry to have wasted other readers time with my stupidity, I'll try to be more cautious in the future.
