Source it doesnt open window

It seems you just have a bookmark for the source it page. That usually means the drag and drop didn’t work, most often because it didn’t drop on a bookmarks bar. You need to drag the source it button to the ‘Bookmarks Bar’ in Chrome, the ‘Favorites Bar’ in IE or the ‘Bookmarks Toolbar’ in Firefox. These are special bars that take a dropped item. They usually appear below the address bar.

If that doesn’t help, maybe you could send along which browser you are using and some screen shots of where you are dragging the source it button?
