Windows 10. If Codebook times out when minimised, unlocking it via the tray icon puts it on the task bar but still minimised. It would make more sense to me to restore the window to its previous position as, as I have unlocked it, I am expecting to use it and not go looking for it.
As well as that I have noticed that occasionally, and often after updates, the window position and size seems to be lost and the default of a smallish window at the top left is used instead of its last position anbd size.
