I searched this when it happened to me and only found a post from 9 months ago where 2 people had the same problem and JF suggested checking for wayward fuel control assignments. So ...

I have 2 screens, with MSFS on the right screen and whatever on the left. When I click into something on the left screen that first click is also registered by MSFS as though the clickable cockpit area extends across my entire desktop even though MSFS is only on one half of it. This only seems to be a problem with the F28.

Long story short, one time when I clicked into navigraph on the left screen the fire switch cover for engine 1 opened on the right screen. I didn't think much of it, when I got back into the sim I just closed it and carried on - BUT opening one of those red covers closes the fuel shutoff valve for that engine. Instead of the fuel valves showing open/open in the white circles, they now showed shut/open. So I turned off the main start switch and tried the reset button conveniently next to the valve, which opened it again and the engine started just fine.

Workaround - don't click straight from MSFS into other programs while flying the F28, start by alt-tabbing out of MSFS to unfocus it, then you can safely click other windows.

Hope this helps someone !

I've just bought the Buxton/Peak Forest extension. When i selected a quickdrive route from Tunstead Quarry to Leicester, there is a problem with the wagons that have been placed in the sidings at Tunstead. They block the tunnel mouth so that you cannot leave the sidings where you start this quickdrive journey.

Sounds like what I saw and mentioned up thread about the same starting point. I think you can delete the offending wagons via the editor as a workaround.
