Mmk, So I was watching Swifty's new movie, and I was afraid he figured out my little teleport bug. So naturally I came here, to see if it was, and it wasn't, so I was pretty relieved. So, instead of holdin out on this lil bug, I think i'll share it.
Mmk, first, you switch to windows mode. Regular, not maximized. Next, you need to put yourself on auto run, preferably towards a cliff, edge, or a giant group of the opposite faction.
After that, you right click your World of Warcraft tab, on the bottom of your screen. Your WoW should freeze up, and then to a person watching you, it looks like you are having one, massive, lag spike. When your done, Left click anywhere in WoW, and you will be back where you where when you right clicked the tab.
Also, yes, I have tested it, and It works for me. if it doesn't work for you, keep tryin, it'll work. ^.^
EDIT: Yes I know, I miss-spelled teleport wrong, >:'(
