[xwiki-users] Xwiki Enterprise 4.5 - Group Admin page not displayed properly

Hello I upgraded Xwiki Enterprise from 4.5-milestone-1 to 4.5 today. When I click on the "Add new group" button in the "Administration: Groups" page, the resulting page contains a lot of empty space that preceeds the actual page. So, I have to scroll down a lot to actually see the page (including the header). Also, the "Create new group" field and the related buttons appear before the page header. I think that I had noticed this in 4.5-M1 also. Other pages are being displayed properly so far, but I'm not sure whether this is the only page on which this is happening. I have noticed this in Internet Explorer 8 and Firefox 18.0.2. Is anyone else experiencing this problem? Thank you.
