By default Microsoft Word 2007 shows paragraph markings even if the Show/Hide Paragraph Marks button is deselected. This can be very annoying and here is how to change it.
[NOTE: Click on the Images to make them larger]
Open up Word.
Click on the Microsoft Office Button
This will bring up a new window. Click on the Display tab on the left side.
Here you will see a section call “Always show these formatting marks on the screen”
Un-check all markings (by default that will include Tab characters, Spaces and Paragraph marks)
