to save changes when you close a Word 2002 document even though
you have made no changes".

I have always been able to just hit the exit button in Word and it asks me if
I want to save my document. I'm talking when I DO make changes. Recently, I
hit the exit button after doing my work, and it doesn't prompt me to save my
changes. I didn't turn anything off, I don't think. I'm so used to just
hitting the "X" now without going to File then Save As that I want this
feature turned back on. Any suggestions?
