Thank you for your response. I understand a layer must be selected and that is what I have been doing. I have a layer selected, the pen tool selected and then clicking in the comp area creates a shape layer with purple dots / lines instead of a mask with yellow dots / lines like it usually does.

I have never used shape layers before and I have no idea how I entered into this mode or how to get out of it. I googled a bit and tried to turn the “tool creates mask” button on but it’s always grayed out.

Thanks in advance for more ideas!
David
