Re: tooltip can be displayed outside the screen

[Richard M. Stallman]

    Sorry I need to give a little more explanation.  In the two images
    Emacs frame is placed on the bottom edge of the screen.  When I
    move the mouse pointer to the mode line, Emacs 22.0.50 tries to
    place the tooltip below the mouse pointer.  But enough pixels are
    not left between the point just below the mouse pointer and the
    bottom edge of the screen. As a consequence the tooltip appears
    partly off the edge of the screen.

Can someone please fix this and ack?
