If you have an unidentified rare item, and look in the storage locker, the wrong right-click hint appears for the unidentified item.

At the bottom of the item description popup, there's a hint for what action right-mouse clicking does to an item, such as selling, identifiying, equipping, etc. When looking in a storage locker, unidentified items will have a right-click hint for "identify", but right clicking actually places them in the storage locker, or back into the character's equipment pack. If you close the storage locker, right-clicking will identify the item as advertised.
