[BUG] - Entire Flight Deck will freeze when using FMC

[avmetroman]

Describe the bug

It seem that if you double press a buttons in the FMC from time to time it will cause the entire flight deck to Freeze

Steps to reproduce

1. Plan a flight
2. Take off and start making change to the FMC
3. Try push buttons twice or scroll up and down the flight plan page.
4. The aircraft will continue to fly but all buttons will be come unresponsive as well as gauges which will freeze on their last input.

Note: I had made a mistake with the flight plan prior to departure and was trying to correct it mid flight. However this did happen to me before on a previous flight.

Expected behaviour

FMC should not cause the the flight deck to freeze

The screen shot provide shows how the AH is level while the aircraft is in a left turn.

I had this issue when trying to put coordinates into a flight plan. Unfortunately I did not get a screenshot prior to closing the sim.

this is a wasm crash, hard to diagnose and not necessarily connected to the fms

Without EXACT steps, this is hard to resolve. We have also fixed several things since this that could have caused it, so I am going to close this out.

@turbofandude Last time I had this issue was scrolling through the flight plan, I did see in the last patch that this was fixed. If I can reproduce it in another situation I'll let you know.
