Frequently I have filled a text frame most of the way with text, but there remains some space at the end that I want to overlay with a text box (it has text unrelated to the main frame). Sometimes it works perfectly. Other times, even though I can see the text frame perfectly well on the board to the side, as I drag it into the frame, the part in the frame disappears. This happens even if there are only these two layers, and even if I deliberately send the larger frame to the back. Why does this happen, and how can I fix it?
Two possible causes are there is text wrap applied to the first frame (or some other object), or the text in the second frame is set to align to grid and there is no gridline within the frame.
