In several missions using standard CFS RAF and USAAF campaigns, as soon as I warp to next action the engine shuts down and refuses to restart. Is it another XP thing? Sorry if it´s been covered before and I haven´t spotted it.

Thanks for the suggestion. I´ve tried it, but it doesn´t make any difference.  I watched the fuel gauge when I wasn´t using unlimited, too, and it did drop, but nowhere near empty.

OK - I´ve tried that now and it seems to work. Thanks! 

Try going to "settings" and check the "automix" box.That will automatically adjust air/fuel mix at any altitude any time. 8)

Thanks. Using the mixture seems to work - I´ll try the automix and see which I prefer. I can see it´s not as realistic, but then to be properly realistic I suppose I would be adjusting prop pitch as well.

Well, that´s interesting. I set it to automix (it doesn´t affect the "realism" by the way - still shows 95%) and it works, With the throttle quadrant visible the mixture still shows fully rich, both before and after the warp, but no engine failure.
Thanks for the tip - now I can get on with the war.

Now here´s another one: in the USAAF Campaign, I take off from a fully scenic Halesworth, but in Free Flight it is just the bare runway. How come? And can I do anything about it?

I'm not sure what Dan told you & don't wish to interfere.

The hangars & other objects you see in missions are defined in the missions themselves. These are mission objects & some will show damage if hit. Using this method the scenery can vary in each mission. The default airfields are usually very basic with just a simple runway for this reason. Some 3rd party airfields include fixed scenery objects like hangars & static aircraft. These are fine in Free Flight or QC but not ideal for use in missions. IMHO
