I'm running windows 10, FSUIPC 4.949p, P3D 3.2 and FSXSE. One button on my flightstick registers 3 button numbers in FSUIPC when I attempt to give it a function under Buttons and Keys. First press registers button 16 second press button 17, 3d press button 18. I give button 16 a function such as pause but have to press it 2 times for it to pause the sim. I tried giving 17 and 18 functions but they don't work in the sim. Only one function works, requiring 2 or 3 presses. I disabled controllers in sim, regenerated a new FSUIPC ini. Same behaviour. I tested the button by giving it a function in sim settings. It works normally. I'm using the CH Pro Throttle, Throttle Quadrant and pedals. FSUIPC only assigns 1 button number to each button on all devices with buttons except for the above-mentioned. Any ideas?
