How to disable Gtalk chat history? Am I missing something or is there no way to disable Gtalk history by default? Clearing separate conversations is a pain. If history can't be turned off, is there at least a way to wipe the whole Gtalk history at once somehow?

(using android2.2)

thank you
Signing out and exiting (may need to check the task manager to make sure it's closed) should clear the local history.
