Re: shell can't stand still

[Richard Stallman]

    When in the *shell* buffer a running command produces output it's quite 
    impossible to scroll back using the page-up key. It seems as if the 
    last output lines are being subtracted from the amount of lines to 
    scroll up ...

    In GNU Emacs 22.0.50.1 (powerpc-apple-darwin7.8.0, GTK+ Version 2.4.9)
      of 2005-03-16 on Latsche.local

That really surprises me.  Once point is no longer at eob, it should
stop moving.

Can you provide a precise test case, starting from emacs -Q?
