WP 2.5.1 issue with add media in IE7

Interesting issue: in IE 7 with WP 2.5.1, the add media pop up box ends up halfway down the page, cannot move it, making it inaccessible. Works A-OK in IE6, Firefox, and Opera.

I rarely ever use it, mostly putting photos at Photobucket and my Gallery page, but, every once in awhile, I upload to create a pop up using Simple Pop Up Images, and would like it to work in IE7. I find it easier to use it for the admin stuff.
