[Plugin: Animated weather widget by weatherfor.us] How do you close it?

Love the look of the plugin. I have tried it in several themes and on several browsers. When I click on the mini version in the sidebar to load the extended info pop-up, the window pops up fine. However, there is no way to close out of that extended information. There is no “x” to close the pop-up window. I have tried back, escape and delete. Nothing. Any words of wisdom on what I am doing wrong? I would really like to use it but I can’t justify it on any of my sites because it creates this stop in the flow. Thanks!
