Blog help needed

One of my good blog friends wrote to let me know she's having this problem:

There is still a problem with your blog - and it's occurring in both Firefox and IE. When I attempt to read a comment, the usual popup box is presented, but, instead of your blog remaining in the background, the entire background becomes a replica of the Haloscan comment box. Double vision!

Are any others of you having this problem? And does anyone know what I should do to fix it?
