Thanks for replying, Woody.
Yeah, i guessed that the text doc wouldn't update in real time, and would need to be reopened to update. When i went to close it, it asked 'save changes?'. I'm pretty sure i had made no changes, i had just opened it to read, but i figured this maybe was part of the update process coming from achat, so i clicked yes to save changes, then it closed. I then opened it up again, and… nothing. The new chat wasn't there. So i don't know what's happening, maybe clicking 'save changes' somehow means that the original chatlog as it was before the last login gets kept…
Both times it's happened, i'm sure it's been when i've opened the chatlog when i was logged in, and then kept it open during the session, so i figure that's got to have something to do with it…
I'll try to carry out a few tests next time i'm online and see if i can figure it out…
