Hi all, maybe one of you can help me... [View all]

Because I'm about to throw my laptop through a window, because every time I select text to alter (say, center and italicize), it changes like 6 frickin' pages of text. I'm using El Cap, Mac Office 2016 (I realize that's my problem right there, but it's too late). Any suggestions?

Note that I'm finishing a manuscript that is like 300 pages long and I've spent entirely too much time with this BS.

Thanks in advance.
