Internet Explorer / Daily Theme issue.

Hi,

I have some issues with the daily theme.
It seems that my site is having some problems with Internet Explorer.
This is the site:
http://treasury.nl

I think this comes because I had to make the width of the sidebar a bit larger.
Can anybody tell me how I can solve this?

Also, I'm getting reports that the login module on top of the sidebar isn't visible. Can somebody with IE confirm this?

Thank you.
