Have a problem with one installation of this set of tools on Pro 2019. We have the latest Fredo6Lib. We have installed the latest JointPushPull plugin. The tools appear in the toolbar. But when you select the surface and then the tool, the tool doesn't become active. You remain with the mouse pointer and it doesn't change to the selected JointPushPull tool.

Any idea why this would be happening?

We installed the same setup on another computer and everything is fine. Thoughts?
