I have had it working before sim update 40th anniversary not added any extra hardware to my computer is there away of countering this or finding which hardware it might be thanks I have now removed all my hardwear and is still the same thing that rudder pedals mouse side stick throttel and keyboard still the same thing happens there another log to look at
Your log is always the same: it looks as if something was calling the GSX menu continuously, so fast that, before the menu could show up, another request to create a menu started so, precisely to prevent the code to be stuck, the old menu request is canceled to make space for the new one.
Since I doubt it's you frantically pressing the GSX hotkey ( I guess you would said it, if that was really the case ), the only possible explanation is either some hardware that is continuously sending keypresses to GSX, or possibly some other addon.
Have you tried changing the Hotkey used by GSX ? Personally, I use X with no modifiers, it's quite convenient to use and it doesn't seem to be used for anything else.
