I was writing a reply to an email in Outlook (Office 2007) and meant to hit Control-B to switch to bold. I don't know what I actually hit, but entire message shrunk to microscopic size. Each letter is smaller than a normal period. Messages I receive are normal and microscopic messages I send are received looking normal, and the To: and Subject: look normal, but New or Reply messages I create continue to be tiny. The font is set to Calibri 11, and if I change it to 200, I can read what I type, but the entire message is displayed along the left margin of the composition window. I have tried every setting, key combination and font to get the display back to normal, but no luck. I appreciate any suggestions.
