I need to reinstall OpenCpn, I was playing with the charts, importing my old track, and added some new chart libraries.... Now it is running awfully slow, like 25 secs to scroll left... I tried restarting, taking out the added charts and tracks, nothing worked. How can I re-install OpenCpn? Anyone had similar problem before?
Problem solved! I turned off the switch for Using OpenGL in the settings, and it works as before! Who would think that the switch for acceleration is actually for decceleration ...
