Take a look at these 3 screenshots taken using the web developer toolbar for firefox. The red outlined area is the current element being highlighted and the toolbar shows the name of that element. I suspect you didn’t intend for these elements to be positioned this way?

(why so much to the right?)

(why so wide, and why does it include the search box)

(look how low it goes)

Also, check when I hover the mouse in the search input field: the toolbar shows

form .login , but nothing about the search div.

(the cursor is a crosshair in the search input)

I suspect that’s a clue to why you cannot access the search input or the search button: it’s “behind” the login form.
