@Daniels118 Hi, me again. I think I found a nasty side effect of the Pan3DView plugin. When I do a "Virtual visit" and walk around after a while the Left-click-drag action to change the direction the visitor is looking will break. It is not immediate, but after a while the visitor viewpoint starts to spin in a wild and uncontrollable fashion with the left-click-drag. I can reproduce even with an empty world space. If I remove the Pan3dView plugin I cannot cause this behaviour to occur.
