I have hooked several voice chat related functions,
for example IsVoiceChatEnabled() and GetVoiceStatus(...)
I have recently learned that they are are used in
FrameXML/UnitPopup.lua when you click a portrait.
This causes a taint and popups with whisper, trade etc are not displayed.
I dont care for the value of these functions in FrameXML but i need to change the return value for other addons as i need them to believe that voice chat is active...
