I was typing a letter today in Microsoft Word 2000. All the letters in the left-hand margin were capitalized, even in the middle of a sentence. I typed them as lower case letters and as soon as I hit the space bar, they changed to caps. I had to go back and change all of them to lower case. My son and I checked all the settings, but could not find the problem. Any help would be appreciated. I'm sure we missed something.
