This is a weird one, but earlier today I found that I was logged in as a different user (RattyBatty). I logged out and logged back in again, which seemed to fix the problem, but then I just noticed that it happened again. Both times I only noticed at first because I've got my settings to see a confirmation before making a trade and RB does not. (Sorry to RattyBatty if you see a few mystery trades in your history!)
