From the original poster: thank you all for the expert advice. I appreciate the expertise and the time that you took to reply to my query, and I'm sorry that I've been so long in posting
I did find the perfect solution to my problem: Uninstall MaxSea
, install OpenCPN
. I really didn't need 300+ mb of bells and whistles, and am very happy with OCPN. Seems to work without fussing around with the system, and to be pretty reliable so far. Time will tell! And it is good to not be using software of uncertain provenance, too!
