hurricane fuel cock used to work fine. Now its broken.

Mines still ok but I wonder if Steam has perhaps slipped in an update? I don't really think so but originally mine would only work if I clicked on the Red part, not the main part of the lever but now it works on most of the lever except the very tip of the Red. I wonder if I changed something?

Just a long shot, have you tried clicking off it but around it? Also if you are using TrackIR look at it and disable TIR so that it remains absolutely steady while you experiment.
