lol seems like this is alot of confusion. What the OP is trying to say, I think, is he wants the search form to be visible at all times in the BROWSER, not the page.
This will fix the form so that it's visible, but it moves it to the left side of the browser;
Not sure why I cant get it to stay at the top right yet. I did ajust your margin a bit to move the form up above the dotted line.
padding: 0 0 0.6em;
