We are using AC 2005. One of our drawings shows all black lines when in the Layout mode. Since I created the drawing, the monkey is on my back to correct it. My paperspace/layout screen normally shows all lines in the same colors that show in model space. Except for this one drawing - all of the colors are black. What have I done wrong? And how can I un-do it? I looked in the help section, but I haven't yet found the answer. Thank you.
