[Zope] Unable to manage/edit Zope

I have Zope installed on two development systems in my office. On the second system when I go to "manage it" http://192.168.0.1:8080/manage, I get the frame on the left frame which shows the root folder and what's in it, but the main frame just shows me the "view" of "Zope Quick Start" instead of the contents of the root folder. I am unable to "edit" it. If I attempt to manage it from another computer in the office, everything comes up fine. Also, when I use this second computer to "manage" the Zope installed on the first computer, I have the same thing. It appears to me that it related to my IE browser, but I cannot figure it out. Any ideas? Thanks Mark
