Right align problem with Firefox on Windows

[crossland]

My new site displays fine using Firefox and Safari on the Mac, and IE 6 on Windows.
However, when I display it using Firefox 3.6.3 on Windows, the right hand column veers off to the right of the screen.
This is using CMS Made Simple 1.8 with the "CMSMenu top + 2 columns" template.

The site is here:

Any suggestions to what might be causing this problem?

Thanks.

It seems, using YSlow to check your css, that the class 'left49' is causing the problem. Set width to 0% moved your content to the left.

Hope this helps.

Yes, you're using the left49 class for the print and it has float left, not needed when it is auto to the left as just a div with no class, you do know you have 2 tables on the left doing nothing, and no need to do all the content in tables, just your tabular data should be in tables...

Now the problem is cuz you give main a set width...
