This is a DNN Module.
You can see the issue at: http://www.smvcuniversity.com/telerikissue.aspx
You will notice that the "available users" list is populated, but you can't see any of the text. If you transfer the items to "assigned users" and then refresh the page, you can see them and if you then transfer them back, you can still see them. Even though they are there, you can't see them when the page loads, although you can highlight them.
