Over the next month I plan on launching a new site and I thought it would be a good idea to use Joomla CMS and include a phpbb3 forum. I am currently setting up a test site using XAMPP on my desktop. I have successfully integrated phpbb and joomla with a bridge but now I have a slight padding/margin problem which differs between IE and Firefox.

Here is a screenshot of Firefox:

Here is a screenshot of IE6:

As you can see, firefox ads a little extra white space on the right side. I believe this is due to something called IE quirks mode?

Any help would be appreciated
