You'll note that I messaged him with "ok message me again to recreate this smegging bug" and then closed the window. He then replied, as can be seen in the acutal chat window, with "indeed" and then I replied "ta", however in the logfile, "indeed" does not exist, and nor will it ever appear later on unless I leave that chat window open for a long time.
Another thing to note that with each time I close/reopen a chat window, it considers it a new session as far as logging goes. This never used to be the case in versions prior to MSN live! plus - it had some sort of timeout where it took, say, 5 minutes of no active conversation before it considered the last session to have ended and the new one to have begun. If I had done the same thing in older versions, it would've simply considered it all one session and logged all text. I figure this may help to pinpoint down the bug if Patchou reads this.
Anyhow, it's 3am here so I'm off to bed. Adios.
