our GPO that we assign to our users was originally created on a WXPSP3 with IE6.
Now we have deployed IE8 to our workstations so I need to apply some IE8 specific setting but when I edit the existing GPO policy mmc is not showing the IE8 settings.

If I open manually mmc the I can see these IE8 specific settings. What should I do to get these IE8 specific settings to show when I edit an existing ZEN GPO?

Or can I somehow import the old GPO settings into a new GPO in a ZEN policy package?
