I can only reproduce this (your last sentence), if I do `M-: (scroll-up)' (same as pressing the NEXT (Page Down) key). When I instead do `M-: (scroll-up 1), I get what I reported in my OP (but I neglected to add that, with emacs -Q -nw, after step 4 the cursor is now at column 83 instead of 70). > X client > ======== > > After step 3 the cursor is at line #2 column #5 (beginning of word > test).

OK, this is just what I originally described, except that I hear the beep only if I press PageUp a second time, which is just Emacs signalling that the invocation of scroll-up was a no-op, since the beginning of the buffer is already visible. > *Messages* contains: > > nil > Auto-saving... > nil > > > On Mac OS X 10.4.9, and no GTK+! Maybe there's a difference in the terminal version under Mac OSX, if you really did (scroll-up 1) and not (scroll-up). Otherwise, you've confirmed the display bug, at least under X. So now it remains to figure out how to fix it... Steve Berman
