In a small text frame, my text disappears when I move the frame to its proper position. A little above or below, it reappears. I've run into this problem in two other places in complex documents; found no solution. In this case, the frame is within another text frame, and overlaps a page number frame and a margin line. Ignore text wrap is on. A little out of place it's fine, but when I position it properly (which is right on top of the margin line) the text disappears. What might I be missing?
