My uneducated guess is that it's a browser issue, I don't know if you can cure it. I use both IE and Opera, and Opera displays a lot of things differently than IE, in some cases not at all.
I was using FireFox and I can't remember exactly what I was trying to do, but I got an error message telling me that it could only be done in IE. So, I take it, that IE is the browser of choice for Auctiva.
