In configuration/items:
An item that is not supported by the client can only be probed again by clicking the checkbox left beside the name and then clicking on "activate selected", while an item that is supported or deactivated can be switched by clicking on "activated".
when the item is changed (from not supp. to activated), it keeps activated until next check. Then it automatically is changed to not supported if it's still not supported.
I would be glad if a click on "not supported" caused an immediate check and switch the item to activated if it's supported.
