This moving search entry is also driving me a little crazier every day. (Mac 10.77.3). I like what @AlbertR said above "If I click on an input field, I do not expect to open a dialog box." At least have it open in the same spot if it does. And also agree with @Paul A. that the truly annoying part is when you want to search for something different. Despite knowing this will happen, I'm still constantly double clicking in the search box thinking that it will select the existing search word currently there only to have me clicking the top of the popup box.
