I can't see/find the issue either between several browsers inc Opera, FF, IE.
*update* I've managed to emulate the issue in Firefox @ 1680 x 1050 res if this helps you

Do you mean between the rotating banner and the bottom of the containing box? if so i dont see it.
Tested on IE7: LISA BLUE and PUBLIC RELATIONS menu is on left not right side.
(remove margin-left from topmodules in template_ie7)
Tested on IE9: Top menu items dont display, probs something to do with cufon.
(Find similar font on http://www.google.com/webfonts and use there much simpler font replacement)
I noticed that you are using tables in that particular area within your <div>'s. I have had similar alignment issues when using tables. I would suggest that you replace your tables with <div>'s or <span>'s and specify the positions. You get much better control over page elements with these HTML tags. Technically, tables should not be used as an alignment tool, but rather as a container for tabular data.
