When I said empty your cache I meant your browser cache on the machine you are viewing the web page in. You’re browser caches (saves) files from web pages you view so that you don’t have download the the same file every time you load a page from that website. Refreshing your page will force (usually) your browser to go grab all the files again, instead of relying on a cached version.
WP Super Cache plugin sets up rules and instructions about what files are to be cached by browsers and for how long. It’s definitely a worth while plugin, but not what I was talking about.
@jasonwiser said he found the layout issue you described in IE7 and what he suggest should work.
