Narrative:

The only way to position the flap handle during approach after slat extension was to move it [flap handle] while rotating the dial-a-flap thumb wheel. No other manner of technique could position the [flap] handle to extend the flaps for landing. While we were unduly focused on the positioning of the handle during this phase of flight; the flaps were finally positioned correctly and checklists completed prior to landing. The workload was less than ideal; but it was decided to accept the circumstances of the flap handle restriction and to not take further time to stay at altitude; hold; and work the problem. On the ground taxiing in; we cycled the flap handle through the positions with normal results. At the gate; with maintenance consulting and positioning the handle; it bound again (2x) during reenactment. A logbook entry made.
