Hi, and welcome to the forum.
Little is known about this problem. I cannot reproduce it. You could try changing the options in OpenOffice → View
one at a time, restarting OpenOffice, then checking to see if the problem is gone. Options are set with OpenOffice → Preferences on a Mac, Tools → Options on other platforms. I realize this will take you some time, however
you are the one with the problem. We would appreciate knowing how you solved it.
