Word 2007 Equations not displaying but printing fine

[BWhitty]

I have a Word 2007 document and I have inserted some equations (Insert tab,
Equations) and after I get done entering the information and click elsewhere
alls I see on the page is a white box with a black border. The funny thing
is when I print the equations display. If you go into the Word Options,
Advanced, I have it checked to display text boxes and drawings and still
nothing.

any ideas?

thanks!
