I should have said to first check whether the window for `*grep*'
is in fact dedicated.  With your cursor in that window, do this:
`M-: (window-dedicated-p (selected-window))'.  If it says `t'
then the window is dedicated; if is says `nil' then it is not.

Perhaps someone else has another suggestion, if it is not
dedicated.  If it is, then you will need to look further to find
out why.

Normally, in Emacs 23, one of those two `special-display-*' options
is used to automatically make a buffer be displayed in a dedicated
window.  But code can also call `set-window-dedicated-p' explicitly
to make it so.

You can also use `M-: (special-display-p (buffer-name))', to
see whether the buffer is special-display (which implies that it
is displayed in a dedicated window).  If the displayed value is
anything other than `nil' then it is.

Again, perhaps someone else has another suggestion.
