It's a long time that nobody write here ...
I have tested your logbook with OpenCPN
260-1524. It seem that it run Ok.
Now, SethDart having updated for plug'in VDR for OpenCPN
260-1524, it was possible to test your plugin Logbook with NMEA
I therefore started the timer and I launched VDR that provides NMEA
data recorded during a previous navigation
This seems to work.
But, when you want to stop your plugin, it is not possible. If you click on the red cross, the plug-in closes but opens again automatically because the timer has not been arrested previously.
It took me a while to understand that.
Could you modify your plugin to set the timer stops when closing the plug-in with the red cross.
Thank by advance.
