I had the same problem and it turned out it was a compatibility problem with the theme I was using. Once I changed themes everything was fine.

Thanks for the reply. I am aware that the problem is occurring because of the duplicated search boxes. I can get rid of the error by removing one of them (I would remove the one in the tabbed box myself), but I was wondering if there was something I could do in the html or css to resolve the conflict while maintaining both search boxes.
Unfortunately, I don’t know enough about either (html or css) to correct this myself. While I have been able to tailor the theme to my liking via trial and error in the style sheet, this alteration is beyond my abilities. You know the saying … A little knowledge is a dangerous thing… 😉
Any assitance is appreciated.
