Hi again everyone, I am having an annoying problem with the auto pilot speed input knob. When I try to increase or decrease the speed on the auto pilot panel the "numbers" seem to "race" up or down and sometimes in the opposite direction!  >:( This of course, leads to sloppy handling of the aircraft as I "race" to stop it before the engines spool all the way up or down and also makes difficult to comply with the ATC if  they were to give you specific speed instructions.  Is this a bug or I am not doing it right? Is this a mouse issue? Would getting a external "auto pilot peripheral" help and can anyone recommend one? As always, thanks in advance.  :-/
