I just got back from designing webpages from a very long hiatus and I am having a hard time recalling everything at once. I have this site located here:

If you will notice, the tables in the navigation area is having problem with the height. I need to make sure the height matches so it will look right.
Could someone please point me to the simple fix for this?
Awesome, thank you for the extra mile. 
Add margin:0; padding: 0; to #nav in your CSS.
PS. I know you didn’t ask for further comments, but all the <p>'s in the menu have id nav, while an id must be unique to a page. You should you the class nav instead, at least for next time you built something like this 
PPS. Tested in firefox, don’t know about other browsers but AFAIK it should work in all of them.
