hooking 'AddQuestWatch'

[Riraito]

Im trying to hook the function AddQuestWatch, but when I put

oldAddWatch = AddQuestWatch
AddQuestWatch = NewAddQuestWatch

into an OnLoad function, the system locks up, and after about 5 minutes I get the error:

Interface\FrameXML\UIPanelTemplates.lua:167:stack overflow

and I find that the 'NewAddQuestWatch' function has run about 15,000 times, if I hook the functions manually, in game, everything works fine. anyone have any ideas on why this is happening, and/or how to get around it?

nvm I figured it out
