Need help with a fluid layout

I have a semi-fluid layout that is causing me a few issues. It's getting very close, but a couple of elements are being pushed down when开发者_StackOverflow社区 I contract the window. You can see it here:

When I shrink the window, the tabs for the table navigation (mid way down the page) are pushing down, as well as the calendar key (to the direct left of the calendar). How can I get these elements to behave properly? I can't seem to make it work no matter what I do, and any help would be appreciated.

Set the ul container to white-space:nowrap and set a min-width on the .ui-tabs, seems to be working properly now.
