Re: vertical-motion in CVS emacs

[Richard Stallman]

    I just tried a fresh CVS checkout (--with-x-toolkit=gtk), and I can
    still reproduce this bug when running under X.

This is disappointing news, but since it worked ok for me after I made
that change, I don't know what more to say.  I suggest that you use a
debugger to examine precisely what happens inside the code that fails,
while it is failing for you.
