Every time the Compass Calibration screen opens it crashes Mission Planner.
Connecting over USB or Radio makes no difference.
All has been working fine for years until the last update of Mission Planner and Arducopter.
Have gone back to ArduCopter 3.1.5 due to other issues, but have uninstalled MP and reinstalled the latest version from the downloads page.
Running Win7 on Fusion VM under Mac OS X.10.10 on a MacBook Pro.
Anyone have any ideas on what has changed with the addition of this Compass Calibration window?
