I have been heavily modifying the Epione theme (somewhat blindly). I thought I was all finished, until I tested it in internet explorer. Oops.
I have at least got the menu/sidebar back up where it should be instead of indented below my page content. However, it now seems to be surrounded by quite a lot of space and be cut off in a strange way, as if half of it isn't visible. This is in a recent version of IE, I think 7 or 8.
Warning: before you click, this is a website for a gay nightclub (but work safe).
How it's supposed to look:

In Firefox it looks pretty neat(I've used a curvy corner code. In IE I will have to add some curved images to the top and bottom of the widgets, but I know about that - first I need to get it to stop being cut off in the middle)
Here's my page/post and widget code.
