Redmine

When using Internet Explorer (both IE8 and IE9), the side by side view (when viewing differences in a file revision) does not have its split half way across the screen, like it does in Firefox and Chrome, instead it is somewhere away off the the right hand side.
i have a large file, which has some lines which are quite wide (wider than my screen). in order to see the right hand revision i have to scroll to the bottom of the page, move the scroll bar over, so that i can see the right hand revision, then scroll back up the page again. not ideal.

i am running Redmine 1.1.2.stable (MySQL)

Thanks
