Hello,
I have a mac (Intel - 10.6.8). I have downloaded
OpenCpn (for the first time) and dowloaded Noaa
BSB and
Enc charts for the
Gulf of Mexico + installed
GPS . But each time I go to look at the
charts in the S-57 format, I get either the coloured
wheel turning or the little watch and it says
OpenCPN S57 file create....users/... library/preferences/SENC.
What is going on? The
gulf of Mexico is fairly big and have busy maps!

Thanks for you help.
