Nana, I can't see the regular store window (the automatically-placed one) in that listing but I can see the three (!) that you added manually -- although the items in them all said "loading image" while I was looking.
By the way, if you're okay with using Netscape, I highly recommend downloading Firefox instead at http://www.mozilla.com/ . It's based on Netscape but is a better browser to have on your computer in my opinion. It's what I use and it works well.
