I don't know if this is a repost or not, I did search the forums for this and had not found it. Though if it is a repost please let me know in a coment..
Ok, as you know blizz randomizes the opcodes not allowing you to view talents or add them, simple fix to it.
Go to your retail wow folder:\Interface\Addons and copy Blizzard_TalentUI and paste in to your cataclysm beta folder in the same directory
Again, sorry if its a repost. I just didnt find it or look hard enough.
