can't use quest items in the quest window

[crazzzzi]

i am having an issue with using a quest item when i click on it's icon next to the watch window. i get an error telling me it's calling a forbidden action, this just started with this update. on a side note i still have no quest blobs in Pandaria, just dots, the rest of the world is fine, i have an open quest in Thousand Needles which shows perfectly
