I have not used the pen tool before and today used it to draw a couple of lines, then went on to other things that I really don't want to have to do over. I decided I didn't like the pen lines but by that time, they were too far back to be on the history (no, they were not on their own layer, stupidly). Then I started layering some textures on top of the image, and no matter what I did, the pen marks are not covered up; they stay on top of the image -- and I can't clone over them, erase them, nothing. If I turn off all the layers, the pen lines are still there, on the transparent background! Clearly I am missing something here. What magic properties does this tool have that I am not understanding?
Thanks.
