joystick jitters

another complexing problem and plea for help! My trusty ol logitech wingman force has started to cut out on the elevator axis with cfs2...it seems to work fine with cfs1...any ideas???????? I've got the most recent drivers for it...and am running dx9 FINALLY (see dx9a problems post...thanks for all the help guys!) Is it possible to use this as an excuse to buy a NEW joystick?! Any recommendations! thanks again!
