Microsoft VistaNovell ZENworks 10 Configuration Management
If bundles are nested 2 or more levels deep, you cannot interact with the icon in the start menu on Vista
This is fixed in version 10.0.3 - see KB 3486285 "Updates to ZENworks 10 Configuration Management" which can be found at https://www.novell.com/support
The problem only occurs with icons in the start menu, not any of the other icon locations.
The problem does not occur if the icon is only one level deep.
