Delete that addon, right now!
You can make your own addon to do the job, like this:
Make a new .txt document, name it CursorMod.lua
Fill this inside:
Code:
function GameTooltip_SetDefaultAnchor(tooltip, parent)
tooltip:SetOwner(parent, "ANCHOR_CURSOR")
end
Make a new .txt document, name it CursorMod.toc
Fill this inside:
Code:
## Interface: 20200
Put both those two texts into a new folder called CursorMod, then put that folder into the wow addon directory.
(you can open toc and lua with notepad or wordpad)
