I’‘m running the 2.0 beta spark. Runs great but uses nearly 40mb of memory! Anyhow, how do I access my chat history? I’'ve set my preferences to record chat history.
take a look in your roster window, right-click on a username, see a popup window open and select there “View Contact History”.
Also, in the next release of Spark, there is a chat history button in the chat room itself.
