text boxes keep repositioning on the page

Version: 2008
Operating System: Mac OS X 10.5 (Leopard)

How can I keep text boxes and other shapes with text from repositioning
themselves on the page? I suspect I don't have the right wrapping settings
but can't seem to figure it out. I'd like to be able to position my objects
myself, and have them remain there when I insert a new object or move an
existing one.

Any ideas would be appreciated.
