I just updated several blogs with different themes. All of the blogs are using Lytebox to "pop up" windows with book information. The only theme I have problems with is Twenty Eleven. The lytebox window displays just fine, but it's missing the Close button. I have looked into this and I know there is an IE8 issue with Lytebox, but I can't understand why it would work with every other blog theme but this one. Is there something in the Twenty Eleven CSS file that could be causing a conflict?
