I get the same problem, press the V and CTD in game mode - Steam install only.
Am only getting back into DCS after giving up making A10 work correctly in DCS World and Tech support took 4 months to come back to me.
Anyway i will try SIM mode tonight, i was hoping Steam would make everything tighter.
