Narrative:

On climbout #2 leading (slat) edge device remained extended causing ctlable yaw. ATC facility was notified of problem and I elected to continue climb 'straight out' instead of making a 90 degree right turn at 4 NM. Leading edge devices retracted at 8 NM and I then made right turn to recomply with SID. Aircraft proceeded to dfw as normal operation. Company was notified by radio 15 min after departure, and maintenance was informed to inspect leading edge devices upon arrival at dfw.
