I am doing something when I type that causes Word to switch to the insert
mode. Then, more typing causes already typed words to disappear. This only
happens when I am replacing a word that has been selected. Please help as
this is getting frustrating. Thank you very much.


That's not insert mode, it's the option Typing Replaces Selection on the
Editing tab of the Options dialog box.
