I think I misunderstood the original question. If I had read it more
closely I would have seen that the window at issue was on the left side of
the text rather than the right. Then I further deepened my confusion by
assuming Jay's reply concerned the appearance of the Styles and Formatting
menu or window which in my experience shows up on the right side of the text
and contains, inter alia, the word "Normal." It can be handily closed by
clicking on a little X. I should have realized that he was talking about
something quite unconnected to Styles and Formatting. So different, in
fact, that I actually have no idea what the heck a Style Area is or does.
In fact, I never knew there was such a thing. Which reminds me of some very
useful advice I received long ago but which, in this regreatable instance,
whizzed right by me: Read the Freaking Question. I could try to describe
how red my face is from embarassment (Very) but that would only prolong the
agony. My apologies to all.
