[jQuery] Thickbox + IE6 - Positioning problem

[jQuery] Thickbox + IE6 - Positioning problem


Hi,
I just launched my new website http://basler-design.de/ but
unfortunately the Thickbox does not work in IE6 right. The window is
sometimes not visible for the visitor and the embedded iframe content
(if you click on the e-mail or "Impressum) is not visible in IE6
either.
Perhaps someone can help me :) I'm new to jQuery, I found these links:

But as I am new to jQuery, I just do not know what I need to edit.
I'd really appreciate any help and suggestions :)
Thanks in advance!
