Tool rotates when I click to paint on it

I was happily working on a sculpt in ZBrush. Suddenly, I go to paint an alpha on it and instead of allowing me to edit the sculpt, it would just start rotating. I backed up to old versions of the same tool, and the old versions do the exact same thing. I tried loading other tools and they work fine. I cannot find a solution anywhere.

ZB4R7 P3?
Maybe it’s masked?
