I'm no expert, but I use Word in a similar way. I like to put my graphics inside text boxes so they can be positioned anywhere on the page regardless of cursor position. I use Word 2010 at home and Word 2007 at work, so I've noticed some differences in the handle documents and graphics. Specifically, the Order option which allows you to move boxes forward and backward on the page. Is it possible all the boxes think they're on a flat plane and they're just pushing each other off the page? Also, it might not be an issue in Word 2010...which is cadillac compared what it was ten years ago.

I hope this helps.
