Hello all, Dock was mostly hidden, and unused in Mavericks (use Alfred etc. to do all my launching). With Yosemite, figured I'd give it another go. Restored/unhid the Dock - but now have these strange icons in it. Presumably(?) they are non-update/Yosemite ready Apps - but I cannot for the life of me, work out what they are. Dragging them off the Dock brings up a little "remove" icon, but releasing the drag, does nothing (no puff of disappearance). Quitting them does nothing either... Any tips? PS - hovering over them, brings up "qlmanage" as the tooltip??
