After changing my layout, I've developed an odd problem, and I have no idea how to go about fixing it. I'll try and explain it coherently: any links or text boxes that appear in the first quarter of the main section aren't recognised - there's a big unclickable region. So if post titles aren't long enough you can't click on them. If the (more...) tag is on the left, you can't click on that either. And when you go to the comments section, the text boxes can't be selected unless you click on the far right. (This is all behaviour in Firefox)
Exceptions: In Firefox, if you are viewing a single post that has a (more...) tag in it, everything seems to work fine. And in IE, none of the above behaviour seems to apply, although the layout is completely snafoo.
If anyone could point me in the right direction, I'd be very happy. The site is at http://evilmoose.shafted.com.au and the css can be viewed at http://evilmoose.shafted.com.au/wordpress/wp-layout.css
