I have an M4 path on top of an M3 polygon. I have M4 selected in the palette, yet every time I try to add a path to the end of the M4 path, the palette switches to M3. I have checked that "select from overlaps" is checked in the layout editor options yet I do not get a popup asking me which layer to add the path to as suggested int he documentation.
Am I missing something? Smart snapping is enabled.
