Just thought I would let you know that last week I sailed nearly 900 miles using OpenCPN
2.1.0 on my notebook under XP.
It ran continuously for 6 days and the program 'hung - up' twice, both times when I had the route
manager open and was fiddling about, both times I had to use task manager to close it down.
Other than that it performed flawlessly - My thanks everybody involved.
If I knew how to establish the cause of the hang ups I would post it here - but I don't.
Hope this is of some help to the developers
