I dont know if this is the right place to do this, since this forum is not gonna be around for long in its current state, but I have found a bug with the new X-mas release Arrow.
It effects the HUD state for all vessels in the scenario, the HUD state will not hold as I change views from 3D to Glass, to 2D panel. It will always reset to what ever state the Arrow has its HUD. Of if I go into the Arrow and turn its HUD off, then every time I switch the panel in say my XR-2, then that HUD will switch off. If the Arrow's HUD is on Surface, then it will always switch to Surface in the other vessels. The second I delete the Arrow from the scenario, this behaviour stops.
