Two goals in the opening 12 minutes lifts Queen of the South five points clear of fellow strugglers Ross County.
The opener came when Sean O'Connor flicked the ball through to John O'Neill and he calmly slipped it past the advancing keeper Jay Smith.
O'Neill then turned provider, sending the ball through to Jamie Adams who slotted home.
County were the stronger side in the second half but could find a way past the home defence.
