Mixture setting problems (Hurricane)

[Redroach]

Hello, fellow chaps,

I am just hopping into the RAF campaign and I seem to have some trouble setting the mixture on take-off (CEM and heating effects on).
Right after starting the first mission, I am in the cockpit of my Hurricane and the mixture setting seems to behave pretty randomly. As you all know, you're supposed to set the mixture to "rich" and then start up the engine. I set two keys for "richer" and "leaner" mixture and, no matter what I do, the mixture setting seems to do whatever it wants at first. For example, "leaning" the mixture suddenly pushes the mixture to full rich (as shown by the little bars at the low-left corner of the screen), throttle at 0% seems to block any mixture settings, prop pitch sometimes influences the ability to set the mixture, too, and so on. This makes it quite hard to set the mixture to full rich for take-off - in fact, it's almost like throwing a dice for what the next key press will do... But, once in the air, the mixture settings work as they are supposed to do.

I presume this is a bug, but perhaps, I'm doing something wrong. Could it be that there are some restrictions in setting mixture, like being dependent on throttle/prop pitch/radiator settings? Is there a possibility that some subtle control settings are in conflict with each other? Any help would be appreciated

CoD is a really great simulation, but it certainly still has to mature, I think. And perhaps, so do I
