Not able to control placement (in regions) of search form

Hello,

First time using an AT subtheme, but I like it.

However, when I try to move the search form into different regions it responds, but there seems to always be a search form in the Header Region (even when the search form block is disabled).

I will paint an example: if I place the search form in region 'none' it will still show in the Header Region. If I place the search form in region 'Menu Bar' a search form will appear in the menu bar region, but the same search form (from when there was 'none') will remain in the Header Region. Leaving me with two search forms.

I have taken a look at the code and scratched my head over this for awhile. I can't figure out where the mystery omnipresent search form is coming from.

Help appreciated!
