On our DF server: P38: Hit start engine button, engine start procedure begins. Hit button again, engine stop procedure begins. Hit Engine start button again: Nothing happens, as if the button is broken or unassigned. Finish mission, start again, and button works. (This occured to me last P38 mission, due to a worn out button.)
 
	Tested following twin engined aircaft that have this 'bug':
 
	- P38, A20B, Pe2-35 
 
	Aircraft tested that do not have this 'bug':
 
	- 110G2, P51D, Pe2-87 (!)
 
	Is it a bug? Can anybody please test, and confirm/deny, and also test for other a/c?
