ok , Iv found out some problems with profile I had set up , it had copied in some bindings from one mode to the next on trigger 2 and this was playing havoc, Iv gone over all my settings in game and in profile, sorted any conflicts( game doesnt like some shift functions) and it seems to be ok now,
@jabo saitek have been taken over by logitek who have released drivers , see here http://support.logitech.com/en_us/product/x52-space-flight-simulator-controller/downloads
I will test next week and see if I have found the source
thanks again for input guys, appreciate it
