I'm building a site at http://www.obscuriscope.com. In the right hand upper corner there's a link to a music page, which (usually) loads a static single page correctly when clicked on. Once loaded, clicking the refresh button causes it to reload the page, only without the entire content area - just header and footer. Any ideas what's going on? I've tried different permalink options with no effect. Sometimes for no apparent reason it gets to where the music page won't load under any circumstances - even when clicking the link from the main page.
