Narrative:

Maintenance was called to address a problem in the cockpit. We think at this time the cross-feed valve was bumped to the open position. Once we were in cruise flight; we noticed the plane had a slight slip happening. We re-trimmed and flew on. Then the captain noticed the fuel imbalance and that the cross-feed was open. Even with the fuel imbalance; we had a very smooth landing that was uneventful. We told the incoming crew what happened and then we proceeded to the hotel. Later that day we found out that the same aircraft had aborted a takeoff due to one of the flap canoes coming off. We didn't know if the slip stream on the canoe while we were flying the aircraft may have been a factor. Anytime maintenance is called to the aircraft; make sure a complete cockpit inspection is performed again to verify switch and valve positions.

Title: On the flight subsequent to theirs; a B737-300 Flight Crew was advised a takeoff was aborted due to a flap canoe falling off. The reporting First Officer believes an out of trim condition from an out of balance fuel load on their flight might have contributed to the failure.
