Carenado C172 - GTN650xi button push not working?

[jcallum]

With the new Carenado C172 I don't seem able to push the knobs on the 650. I don't get the finger icon at the cursor and the left mouse click doesn't push the button (e.g. lower right button to change com radio to nav radio). This does work fine in the Carenado C185. I am in VR and in the SU4 beta.
