I downloaded the eletro widget, installed and entered the code as described in video. While logged into the Admin site, I can see the widget appearing on my website with the drop-down menu of widgets to select from. However, there is no "add" button appearing. I only see the "apply" button and 3 others (clear, restore, etc). Any idea of why the "Add" button does not show? I'm using WP 3.0
