|I really wish I could provide more information on this, but I really just don't know what's going on. Somehow, I'm getting two tooltips no matter what I select for settings so long as I'm trying to get it anchored to my cursor. I don't know if it's the same for <i>every single permutation of the settings</i>, because, frankly, I don't have the time to test that many. @_@ I also can't tell which tooltip is being shown at my mouse and which is being shown at the bottom right of my screen, but here's what it looks like.
After disabling all other addons and running a few more tests, however, it seems to only happen when using TinyTipExtras. (The pictures show "compact mode" but I believe I tested it as the normal mode as well with the same results.) In the pictures, the tooltip in the bottom right is what I'd actually like to see at my cursor - is this your tooltip or the game's?
