Throttle Problem: Joystick Cannot Fully Throttle Back (X-52 non-pro)

[ultrablue2258]

I am running DCS with Windows 7 and using a Saitek X52 joystick and throttle. Until a couple of days ago, everything worked like a dream, but now I cannot get the throttle to fully reduce power A full calibration and test of the Saitek shows that it responds correctly and fully on all axis but in DCS the throttle, pulled fully back, only reduces power down to about 50%. My short term solution has been to change the throttle axis to the "Slider" button on the throttle and this does produce the full throttle movement in DCS - but of course I'd much rather be flying using the the throttle handle. I've tried everything:

Running for a USB 2.0 port

Checked the potentiometer

Tried in all USB port

Uninstalled DCS (1.5 and 2.0)

 

Any Help will be appriciated
