Some mac compatibility help, please...

So... this is a beating-my-head-against-wall moment and I am too close to the problem to get a great angle on it so I am throwing myself upon the board's wisdom and all-y'all's collective knowledge.

I am trying to make a very specific client happy. My layout works on PC just dandy and validates (minus the obvious height hack) but seems to be breaking on macs. ANY help would be great. The following link contains the xhtml with an screen grab of how it should appear:

And here is my CSS:

Any help is appreciated and I thank you in advance...

EDIT: So here is a reference as well:

Note that this problem is occuring ONLY in IE 5.2 for mac... what is the bug I am missing here?

For all those with a similar problem, the issue was in the CSS within the background-image: url (path/to/image) IE 5.2 seems to want double quotes around the path/to/image

Anyways... thanks all if you reviewed and tried to help
