Hi there, many thanks for your reply, yes, that makes sense. The problem I faced relates to the bindings changing after I had set them all up initially when I first installed MSFS in March 2021. The hardware itself remained the same (Thrustmaster HOTAS Warthog throttle, joystick and rudder set). MSFS ran perfectly with the bindings that I had established and tested from March to September 2021 however, somewhere down the line after October 2021, a compulsory update was released and one of the bindings that was set by the update (it looks like it was the mixture binding) created the throttle issue. Interestingly, my versions of DCS and the IL2 Battle series have retained their hardware settings over the last eighteen months even though the packages have been updated multiple times. What I have learned from the issues that I have faced with the asobo changes is to make sure that I retain an up-to-date copy of all of my stable bindings and, in the event of future problems, compare these bindings to the current ones and look for any differences. The good news is that the bindings are now stable and everything works exactly as it should which is a big relief ! Regards, Ed
