I am writing a Word document using a table. I always write in 12 point type but, every so often - usually when I cut and paste something in or start typing in a new box - it suddenly changes to 14 point or 10 point type.

I only ever use 12 point and I have never used 10 or 14 point. Have I imported something in 10 or 14 point type? Not as far as I know and, even if I have, this seems entirely random.

I don't think it's a style thing. If it was, the style would be either 10 point or 14 point but not both.

I type Control A, change the point size for the entire document to 12 points and , as short time later, back come the 14 or 10 point type again.

Anyone got any solutions?
