I have had some strange behaviours also....
My idea is that something goes wrong after pressing STRG to enter text in de MCDU...
I have changed my handling, for me I now NEVER use the keyboard and enter all data via the mouse/keys in the aircraft. No problems like these since then.
Still the same in 1.0.9....
What I noticed: It seems it is triggered If i add text into the fms, like ZFW, BF, CG , in the moment I press STRG ...........
I gave up if i read the new changelog of 1.0.9........
added .. added .... added.
It seems that hte core problem of wasm crashes and CTD has NOT been fixed.....
stop producing more and more bugs. come back to the roots and bring us an usable airplane we have payed for.........
quit your script kiddies, hire some guys to code some more realistic systems 😵💫
