I'm running W8.1 and I've install againg the Queen update 2.1 etc... sometimes no rudder no control at all from my CH Eclipse.it'Is like FSX, when flying 747, desactivates the controls but is not produced when I fly standard plane from FSX like 737-800 or cesnna. It occurs only with PMDG 747-400 and AIRBUS X Extended. Never seeing before with other PCs. XP or W7. Any help please?
