Add Content Popup Form Buttons Don't Work? - Ajax

Greetings - thanks for your teams great work! This has saved me a ton of work and allowed me to get on to the testing portion of my project. I have a strange problem that when I try to use the popup form to add content to a lesson, none of the buttons seem to work. I believe this is an Ajax form. I am specifically at the Courses --> Ouline-->Child Pages page, I click on the "Add Content" button and a popup appears. I can click around and select the different radio buttons, but when I try to select the "Add Content" button it only changes the button image to highlight it like it has been clicked. Nothing actually happens. I have noticed also hat some of the messages that are displayed I cannot dismiss by clicking the X, but others I can. I am viewing the page using Chrome, on a Win7 box but I get the same results on my Win 2012 server using IE 11. Thanks.
