Novell ZENworks 10 Configuration Management
If you launch a Quicktask successfully, for example at the devices screen you do a Quicktask for all workstations of "launch application", then let that conclude. Then launch a Quicktask for all servers, such as reboot/shutdown - the "launch application" dialog is displayed
This is fixed in version 10.0.1 - see KB 3486285 "Updates to ZENworks 10 Configuration Management" which can be found athttps://www.novell.com/support
This problem does not occur if you perform other actions in-between, only if the Quicktasks are performed one after the other.
