I'm using Outlook for Mac 2011 version 14.6.3 and whenever I type an apostrophe and sometimes when I don't physically capitalize and "I" (i.e. let auto correct handle it) or even the first word in a new paragraph, the alignment of the entire message switches on it's own from left to center.  In the middle of a sentence, if an apostrophe is typed, the entire sentence jumps to center alignment in the body of the message. Any ideas how to fix this or why it is happening would be greatly appreciated.

Thank you
