Change themes and get rid of the iframes. Did you realize that for the most part, search engines don't "look" at iframes. Ignore them. That's what was meant by the "spider" comment above.
Iframes were meant to be accents to a web page, similar to tables. Tables are for data not design. But they look like something familiar and easy to use and people get way out of control with them.

Honestly, you will be much better off with a Theme design that doesn't put so much into an iframe, and then you can spend more time on content and less on fussing with the design.
That's my new motto. Less with the design stuff and more effort put into great content! Let's lift the whole WWW with high quality intellectual blogging and writing! ;-)
