Scrivener Inserting Peiods

Hi there.

Every now and then, while I’m writing my prose, periods will just randomly insert themselves into my text, for no apparent reason. I’m not sure if it’s Scrivener doing this, or if it’s TextExpander doing it. I’ll have to disabled TE and see if it solves the problem. But, it’s REALLY annoying, so I thought I would post it here just in case anyone else might be having the issue, on the off-chance that it might be Scrivener doing it and someone else was having the same issue. Anybody else notice this behavior, or am I the only one?
