Lena. I was having similar problems. I recomend you try using Avant Browser. You can download it free :
www.avantbrowser.com
It's a great browser and allows you to open extra windows within the same program so you can quickly go to other pages within auctiva and keep the one you are working on open.
It also imports all your bookmarks from IE.
Takes a bit of getting used to but may well help.
