CSS/PHP Issue with XOOPS CMS theme

I need somebody who can fix what appears to be a very difficult CSS/PHP issue. I have had several people, including the creator of the theme look at this and was unable to fix it. I am running a XOOPS site, with a theme by Graphics-Worx called “GW_Business1”. I have a login bar that is stored in a frame at the top of the page, which is consistent with other web sites on my “network” of community sites. The problem we are having, when I add my logo, navigation bar, flash banner and the login bar – something is throwing the theme off. It works fine in Firefox at all resolutions. However, when you view the site in 1024*768 in IE (version 6 & 7) the site appears to overlap. When we remove the login bar, the overlap disappears – but the frame starts to stretch changing resolutions and forcing a scroll bar in 1024*768, which isn’t workable. This is an adjustable theme, which will adjust to any resolution 1024*768 and above to fit the screen without scrolling. ALL GENERIC replies/replies will be ignored, I need somebody who can fix this and it needs to be ASAP – as my site can’t run with this being down. Somebody who is an expert in CSS & PHP should be able to fix this easily. I want to work with somebody online during the day Sunday, October 22nd. You need to be available over MSN. I am in Ontario, Canada (Eastern Canadian Time Zone). Thanks.
