Cut out animation problem

Hi there,

Another question. I was drawing up my character rigs on different layers (so layer 1 = body, layer 2 = eyes, 3 = head, etc). When I went back to fill in colors, it wouldn’t let me select my drawn object. It just remains unresponsive - I can’t fill in colors, I can’t select lines, I can’t re-draw on the same spot, I can’t draw or edit anything). And the layers are not locked.

What is happening? D:
