The knobs continuing to turn is not an aircraft specific problem, has been around for a while and is reported in other threads (not easy to find as the search engine in this forum requires that you use the exact right words). The solution reported is to not adjust the knob by clicking it.
Move your mouse over the knob until the tooltip appears, then adjust the knob only with your mouse scroll wheel. I’ve always used this method.
This post gives a couple of solutions you could try.
