I've come across this problem for the last 2 days. I'll pick a mission I made in mission editor, Start the engine (or the first engine if there's two), and then.... no control. I can look around using the mouse for FC3 planes or move the yellow + around if it's a clickable cockpit but the keyboard and stick are useless. I can't even exit unless I use ctrl alt del. that seems to be the only keyboard function that works after the engines start.
I repaired dcs using command prompt... no joy.
I restart the computer and it works for one session but if I turn it off and start up again later.... same thing.
Anyone have a clue what the problem is?
I'm using a brand new laptop:
Cyberpower VR XPLORER X7, I7 7700K 4.2 Ghz, GTX 1080, 16 GB RAM, 2 TB HDD.
Everything considered there shouldn't be a problem running DCS.
