MS Word Series: Equations Are Displayed as Empty or Shaded Boxes in Microsoft Word

Very simple problem but extremely annoying!!!!

I assume this problem happened after I had installed MS Office updates.

I could write and edit the equation written with texsword & MS equation editor 3, but the image displayed was plain gray shaded empty box.

Turns out, the workaround was very easy as explained in MathType TechNote 74. In my case (MS Office 2007), navigate to:

1. Ribbon -> Word Options -> Advanced -> Show document content
2. Click on the third option: Show picture placeholders

Done!!!
