Where are the options to remove the shadow from the search box? My Site

It looks like you figured it out.

Ya, sorry to bother so prematurely. Thanks for taking the time though!

For those who my be searching the forum for how to do this:
Click on Atahualpa Theme Options under the main wordpress menu Appearance.
Click on the Style FORMS under the Various Content Items heading.
It should be the 1st box.
