[Plugin: plus twit like] hidden window

This is a great plugin. There’s only one problem. If you try to send using the facebook icon it always opens a popup window below the icon. This doesnt work if the icon is at the bottom of the page, as the window opens up off screen. It would be good if it recognised when there is no space below the icon and automatically opened the window above the icon instead.
