I removed plan G files folder and did clean install.
There seems to be something going on with context menus??
Now, when I go to the Data Tools button and click on the small arrow in the lower right corner,
again Plan G crashes immediately.
Log doesn't show any errors this time.

However, I am able to add waypoints to a flightplan now, so I'm good for now.

When I create a new flightplan and try to add a waypoint by right clicking in the map,
Plan G immediately crashes every time.

I'm on Windows 10 and tried both v 3.1.2 and v 3.1.3 beta

Has this been fixed?
I still get a reproducable crash by

- right click in the map
