Sometimes when opening a BoD book, the area to the right of the gump becomes off-limits (ie if my backpack is there I can't highlight anything), and if I try dragging this off-limit area, the BoD gump gets dragged. When dropping BoDs into a BoD book within ~1 second (this has happened with dropping items into secure containers as well), sometimes my UI bugs out (or it is anti-cheat code) and I cannot drag any item, I get the message "You cannot move that." (some message like this). Has anyone else experienced these? I am not using any external programs.. the "You cannot move that." bug especially annoys me as I try to finish sorting my BoDs as quickly as possible; now I need to force a second pause in between. And yes I reported these.
