Time runs out, but then does not cause a winner

[billzuercher]

When playing human versus computer, Winboard does not declare a winner when time runs out (for human at least). The clock puts up negative time values, then goes to positive time values, allowing game to continue.
Is there a way to end the game with a winner when time runs out?

Are you sure the option 'auto-flag' was on? (In the General Options dialog.)

No, the auto-flag was not on. Thanks for the reply.
