If you con control the order, you can make sure the first follow-mode window is rendered first, so you can set the window-start of the second window before it gets rendered, etc... IOW, controlling the order of window display lets you solve the issue of determining the window-start for subsequent windows. > Currently Follow Mode fights with the display engine to get what > it needs, often resulting in delays of several tenths of a second in the > subsequent redisplay operations after the first one. That's why I'd hope that if you add a hook so follow-mode can tweak the redisplay from inside, it should work much better. Stefan
