Anchoring issue in Word 2010

[Maky]

I have a full-page illustration inside a drawing canvas, and I'm having problems with the anchoring. No matter which paragraph I try to anchor it to or what positioning/text wrapping settings I use, I keep getting half a page of text, following by five pages of single lines of text, followed by the illustration. Following the illustration, things go back to normal.



What the heck is going on?? It should just be a simple object with a simple anchor, following simple rules for positioning and text wrapping. I realize that since it takes up a full page that it will create an artificial page break, but what's up with breaking the previous paragraph up into multiple single-lined pages??
