I'm having a very confusing problem w/my theme right now. If you check out my index page at http://underhyped.com/, you'll notice that there's a big space between the searchform and the bottom of the header.
If you click on a post and go to the single.php page, this space disappears (and the text below the searchform is the right size--it's too large on the index page).
Does anyone have any suggestions about what might be causing this? I really don't understand what the issue could be, since it should be calling the same sidebar. How can it show up differently when it's supposedly the same file?
