My test site is here:

There are several graphic issues that I will fix, but right now I'm working on the ajax tabs. I put a google map in the first two, and another page in the third tab. When you load the first page, the google map comes up fine, works great. If you click on the second tab, the map does not display...and if you click back to the first tab where the map worked before, it is no longer there either. Any ideas on what I'm doing wrong here?
