Have run into a strange problem with Microsoft Word 2000 (a part of
Microsoft
Suite). I can't change font size or use bold, italics or underline on the
document page but when I go to Print Preview it shows the changes and it
shows the changes when the page is printed. It seems as though something
blocks the changes from showing on the document page as I type in info. Is
there a block somewhere with a check mark that should or shouldn't be
there?
