Great! That's just Great........

Made it to the gate okay with a bit of A/T minimal power (4knots) to correct the steerage swing on taxi

Unplug and plugin again as Microsortout Sidewinder page suggest 3 or 4 times (but a bit hard to do at 1nm out without a first officer)
Prior takeoff on this long haul and all four were okay on power to V1 using joystick throttle. -----------Annoying little gremlin usually only on landing!
A standard sidewinder which I am normally happy with and only happens on irregular basis both for two and four engine a/c.
Anybody else get that? :-?
(I cannot replace her as there are no shops and none available where I am living and working so you can understand my request)
P.S. I now save all my landings before the downwind legs.
