I was working on my map, and as of yesterday, drawing paths and contours resulted in nice, smooth curves. Today, I get the curves, but I also get a greyish white set of lines that define the curve, as well. Obviously, this is mucking up the map horribly and I'd like to kill those lines. I'm sure I touched something, but I don't know what, and I'd really like to avoid redoing today's work or starting from scratch. Does anyone know what I did and how to fix it?
