Hmm I like what you've done to the Metro theme so far, will be nice to see this finished.
I'd guess try adding this into your additional.css template:
Code:
#navbar .selected + .floatcontainer > li a.popupctrl {
float:left !important;
clear:right;
padding-right:none !important;
padding-left: 10px;
}
That should do it if not let me know.
Edit: Also the search is not clickable, hard to identify using firefox too so that means its under another div, I'd also address that in the style as well.
