before 5.2, i could alt-tab during flight points and when I landed, i could alt-tab back in and i'd be at the flight point, no issue at all. but now, I get a loading screen.
even weirder is that when NPCscan goes off while alt-tab, it doesn't actually respond anymore until i'm back ingame. now, I already have all MoP rares, so no problems there, but it gives issues, and i wouldn't be surprised if the same were to be true for other addons.
and when I'm alt-tabbed in shrine of 2 moons, and then tab back in, my framerate takes a monstruous dive, like from outer space into a 10 mile deep pit filled with barbed wires and shit, and this is only partially solved by /reload.
have they really botched alt-tab so badly? I had none of these issues before the patch.
