Is there a way to put the close button on the top of the float box as well as the bottom. In my app. the user has to look for the close X at the bottom and are missing it. Thanks in advance.

showclose -> Enables/disables display of the close button in the bottom right corner. like this:
<a href="'your link "rel="floatbox" rev="showClose:false ">you title</a>

and put button no the box :
<button onclick="fb.end()" type="button">close</button>

or use rev=" infoPos:tl controlPos:tl"
<a href="'your link "rel="floatbox" rev=" infoPos:tl controlPos:tl ">you title</a>

Floatbox v3.24 - Options: http://floatboxjs.com/docs/options.html

controlPos:tr (not tl)
As for two close buttons, I don't think so.
