I put my Surface Pro 3 to sleep last Thursday mid-day and went to a conference. I didn't turn my computer back on until this morning. 1Password was unlocked when I put it to sleep, but is set to lock after 2 hours, which in the past it has always done even when I'd put it to sleep and wake it up in the morning--it would be locked. This morning, 1Password hadn't locked since last Thursday, it was still signed in and in fact I used it to sign into this forum :-) Something with the locking code has changed...it should definitely err on the side of locking if the system clock has moved 2 hours (where 2 hours is the lock timeout in preferences) even if the system has been asleep!
