Yes it says IE9 Standards. Sometimes the issue isn't there immediately visible on popup, but dragging it around it's definitely noticeable. I've tested it on three separate machines all running IE9. It's almost as if the outside border of the message-box is being moved independently of the contents, and they don't always align.
I tested this on a fourth machine with a similar setup (Windows 7 64bit Running IE 9) and did not see the issue at all. I'm going to investigate this further, IE settings etc. and see if I can determine what's going on.
