There's a bug in the current CN2 software release that over time turns into a serious performance problem. The cause is simple: some of the diagnostic logging functions used in the software development process didn't get switched off for the public release. Over time, the diagnostic file gets big and the time required to append this file gets outrageous.

The work around is just as simple: run the updater as though you were adding waypoints or airspace (you don't need new files on the USB, just select e.g. "waypoints" and run the updater). This will remove the diagnostic files and restore performance.

Didn't notice, updating airspace and waypoints regularly. Things change!
