When I am in Word, when I type the original text everything is fine. The
spacebar adds space. But if I need to go back into the text, if I press the
spacebar, it erases the text. It will simply eat the letters rather than
adding space into the area. Also if I want to add a word somewhere in the
text, that also eats the letters of the existing words. What setting is this
and how do I change it?
