My silkscreen layers seem to be locked and I can't select any objects on it. I can create new text items but not change them!! I can place new objects but not select or edit them again. I have the top silk layer selected as the editable layer, and I have created a new PCB and in the new one I can edit text items in the new PCB. This happens on both the web version and the desktop version. Is the PCB file broken? Could I have accidentally locked an entire layer? Plz help!
