The difficulty of what I've done is a far cry from trying to read action bar contents (I assume thats what your getting at). I havn't needed to know anything about what WoW holds in memory. The only people who may know that are probably not in Blizzard's good books!! I wonder if Blizzard would ban this if it were publicly released too. I am not going to spell out hooking WoW for you, but C++ would be neccessary no doubt. http://www.ring3circus.com/ is one site I found useful... has a good list of tools. 8o
