In Excel: Put your cursor in a cell. Click Window/Freeze Panes and it will
freeze everything above and to the left of your cursor.
In FrontPage, it requires frames. If you have a frameset with a frame on
the left, a frame on the top and a third frame in the middle, it'll behave
the same way. The middle frame will scroll while the other two stay in
place. Of course, you don't need two outer frames, nor both a row and
column in Excel -- you can freeze just one if you wish.
Actually, in FrontPage, any of the frames will scroll independently of the
others, but the most common use is as I've described above.
