I sent the message below to the developer via email
yesterday. He emailed right back!!
and said he'd seen the issue before but couldn't remember the solution. He suggested posting
here to see if anyone has any ideas.
I downloaded Opencpn
a couple of days ago onto a machine running Ubuntu Linux
. It runs great, and I'm much impressed. NOAA raster and ENC
charts just run phenomenally and all your most recent improvements (mousewheel zoom, etc.) run great.
I then found two CM 93 cd's on the Internet
and downloaded them through a torrent download. I unpacked them using Ark software
. The files all appear to be there. But when I try to load them into Opencpn using the wrench icon, I get only a brief flashing of one brown bar on the lower horizontal bar. Then the brown bar disappears, and none of the CM 93 charts seem to be there.
I'm thinking this may still be an unpacking/unzipping problem. The CM 93 files appear to have been zipped in 2004 using Winzip 95. Does anything strike you immediately as a possible solution?
What a cool program and a wonderful thing! I hope this is an appropriate and useful bit of feedback and inquiry. Thanks for all you've done!
