Hello,
I can imagine that this looks like a total noob question, but I think there's a little more to this problem. I've had this problem before, then it went away, now it back again, and I can't figure it out.
I wanted to remove a tumb that caught the corner of the lense in a shot with the clone tool, so I choose my clone tool, select a copy of the background layer, and press alt to select my source. It doesn't work! I don't get my little plus thing. I've also noticed that I can't select part of the photo with the lasso tool either. I AM selecting the proper layer on the side! I don't get it, why isn't this working?
I've tried resetting the tool, I've tried several different files, it just refuses to let me select a source. My alt key is working, ctrl-alt-del says so. Just frustating.
Thanks...
