Same here on Windows XP for some value of "almost". Irreproducible with Emacs -Q. Does it happen with Emacs -Q on your system? FWIW, here the buffer in the "other" frame does not scroll but its window's modeline values change to the same as in the other frame. Maybe Stefan's attempt to synchronize selected frame and selected window misfired. Pure speculation, of course. martin
