Having 50/50 chance of the rotate tool not accepting an arrow to lock orientation. It seem sometimes if I drag along an axis to select my first reference for rotation the tool thinks it should change the locked axis. Here in the video I selected the point, tapped up arrow, then tried to start rotating (I need to rotate this 90º in plan).

Been fighting with this today on a framing model - have already re-started SKP to see if it helps.
