What you listed above is not likely to affect the height of a window - it's the header, mode and tab lines that count more. > That, the fact that this code has been there for a half year without a > single reported crash (if resizing a window is enough to trigger such > a crash, that would surely have happened already), and the fact that > get_narrowed_* is not executed at all in the ediff control frame, > means that there is a bug somewhere else. Don't worry. What Po Lu saw is something I've seen in different forms much earlier. Small frames can be a problem for redisplay. martin
