After I install the logitech s/w, or later try to calibrate, the throttle as indicated on calibration window moves opposite to my throttle input.

Vista-64 bit & drivers (logitech has a 64-bit one).  I also tried to install the 32-bit drivers (and told Vista to run it as such with admin privlg, thinking that might work.  The 32 told me I had to use the 64.   

All the axis, buttons, etc., function and calibrates as it should.  It's just the throttle is messed up, and on this computer.

It works fine on a different (but similar h/w specs) rig with 32-bit xp prof & logitech 32 bit drivers

TIA
