This was a problem before the latest patch.
It’s better to “hover” over the control, then use the center mouse wheel to either turn the knob or the dial. It works, but every so often you will end up accidentally zooming in or out of the cockpit view if your hover wanders off target. This is a good operation to do while using Set Pause.
Edited to add: When hovering, it’s best to have Tool Tips enabled so you know you’re hovering over the right spot to actuate the control.
