No, not being rude but having encountered this in the A320 and 747 the problem seems endemic to all aircraft. Just tried setting the altitude in the C172 and after clicking the Alt knob, it started spinning and only stopped when it reached 99,999 feet. Others are reporting this on the Steam forum.

Seems to have been introduced with the last patch, not had this before. Guess it's time for another Zendesk report...

For what it's worth, I have no issues with this in any of the airplanes you listed.

I've seen it in previous builds and saw it again last night after the patch with the A320. Just another one of the many "quirks".

Ah, I thought it was just me! Reassured that I'm not the only one.

Im running on quite an old computer and not had any of the common issues people have been having with this sim but, since the last update I have had problems with the sticky altitude and speed knob. Becomes a nightmare when you are trying to get to lower altitudes and it spins down to 0. Has anyone found a fix for this yet?

Yep, does it on the VS knob in the CJ4, does it only when you click it. If you use your mousewheel its ok.
