The terminal (e.g. xterm) is resized by the user, of course. dialog doesn't recognize.
To reproduce: Do an upgrade of your system within an xterm (using dialog as the front-end). If there is a config-file-has-changed dialog, then show the differences. Resize the terminal while the diffs are still shown. Leave the diff using 'q' and try to show the differences again. This time it should have used the new terminal size. Regards Harri
