Thanks Serge, I experienced this problem on version 3.2.0. I downloaded 3.2.2 Build 2013-05-08 and it behaved exactly the same.
However, the problem has since resolved itself. I'm not sure how or why. For information I did the following:
1. Attempted to restore the operating system (windows 8.0) since this was the only change since OpenCPN had worked properly. The restore failed. I got a message saying that the C: drive had errors.
2. Ran CHKDSK which found no errors.
3. Just for drill I added some NOAA rasterscan charts to my library and behold, they worked fine (so I thought maybe it was only charts I had created?).
4. Checked my charts again, and...It all works!
So, right now, I don't have a problem. Possibly I never did, could have been I just didn't zoom in correctly to reveal the charts, I don't know. Meanwhile, I checked my back-up computers
, which both work
