Uncommanded rudder movement

What th-!?
Suddenly most of my default and add-on FS9 aircraft rendered unflyable by very sudden uncommanded movement of rudder (haven't checked them all, but...). First time I checked sensitivities/null zones, they had changed (?). Reset them; worked for one a/c, but not another. Went back to a/c that was OK a moment before, and... spastic rudder again. Checked sensitivities, etc: they had not changed. Not good. Hard to even roll down the runway without aircraft veering, tipping, and crashing. Can't fight it w/rudder bar.
What's different since I last had the rudder working (finally) as I wanted it for all my planes, you might ask...?
1- re-installed CFS3 and re-calibrated X45 for that game... changed a few button assignments in CFS3.
2- downloaded/installed 3 a/c from fsdownloads. Have since removed them and restarted sim a few times, but still dealing with "possessed" rudder. Anybody seen this before?
