Strange theme options problem.

I’m building a theme with an extensive theme options page. I’ve built several themes before this one and everything always worked fine. However, with this theme the theme options link shows up in the sidebar, but when you go to the theme options page the body of the page is blank. But, when you view the source code you can see my theme options pages html. Reaaly kind of stumped on this one. Tried deleting and re-installing the theme, clearing browser cache, renaming the theme, but still no go. If any one has any ideas on this please let me know. Thanks.
