I am using V25.000 (build 996) on a Dell Precision M4700 w/ NVIDIA Quadro K2000M, with software installed on the only hard drive in the system (SSD).
The layer control seems unpredictable in the following way. I can select entities, select change attributes, select change layer and all appgears OK, however when I try to hide or display the layer that I sent the entities to it does not show/display according to the layer that I selected.
Also, I can click on the layers icon & set the active layer (shown by the red check mark) but I cannot click on the show/hide icon (black or white square to left of layer icon) to select which are displayed as described in the help menu.
Tried sample file "2D Sample' by adding new layer, selecting the arc in the middle of the part and modifying attributes to newly added layer, then turning off that layer, did not work.
Any insight on this would be appreciated.
