deleting selected history objects in the library does not delete them
when doing a search in the library for certain history links, then deleting certain links within that search either does nothing, or removes them from the screen for a moment, only for them to return. The 'forget this item' in the right click menu does remove them, but takes a whole second to process and can't be done on more than one item at a time. This isn't an option when one wants to delete 400 some links out of a 500 link field that's already within a search.

Does removing a single link work?
