Controls working... sometimes

[slm]

Same thing here. Usually when playing a quick mission controls work at first, but they stop working after some flying. Sometimes I may be able to fly several minutes, sometimes just a couple of seconds.

When this losing of control happens game controllers no longer respond, some views still work (f2,f3) but I can't switch to cockpit view.

First I thought this would be about AI Control becoming active, but I have checked option
No AI Control.
and it seems it doesn't help.
