More details...
My OS is Win7 Ultimate 32bit, Phenom X4 940, 4GB Ram, GTX 260 and trackir 4. Every game i play the buttons on my X52 PRO (latest driver and software) stop responding for a certain amount of time then all of a sudden, every button pressed while it was not responding start to send command in sequence. When I ALT-TAB and go to my joystick properties panel. Every buttons respond perfectly. Also it seems that its only in Blackshark. Tried different flying games and did not encountered this behaviour. I even tried to reinstall Blackshark, drivers, etc in every order possible. Help!!!
