I have searched and searched the forum for an answer to my question??
, beta version, same issue with 3.0.2, Win7.
I have been using OPEN CPN
with C93 charts
for a number of years and have been very happy with it.
I recently added a number of Noaa ENC charts
of FL and the SE USA. For some reason when I have these ENC
charts selected I get a " U " symbol plastered all over the chart. With CM93 charts selected, no symbol??
I assume that it is some sort of general warning but I have been unable to find the meaning???
