Eystein,
I checked with one of my colleagues and this is related to a Known Issue. Please see the Configuration Manager 8.1 Release Notes, Known Issues section:
"When using Configuration Manager in a Windows 7 environment, the links on the left side of the Details pane for a selected object are sometimes disabled.
Workaround: View and edit the content of those links in the Properties dialog box of the selected object."
If you have further questions, please open a case and we would be happy to help.
Thanks,
Roger Farr
