If a character moves away from a square adjacent to a monster, the monster gets an OA. Good. What happens after the attack is resolved? Can the character continue moving?
So far, I've houseruled that if the attack misses, the character can continue his movement, but not if he is hit. I'd like to know if there's something official.

From Opportunity Action,
A normal OA will not interrupt movement. Even if the creature is hit, it can continue it's movement as normal.
That said, it is possible to stop the movement, but you'd need a power or ability that explicitly says so. For example, the stance Defend the Line would allow the fighter to slow the enemy on an OA. The creature would then only be able to move a total of 2 squares for his current move action. If he has already moved 2 or more squares, he stops in the square he provoked the OA from.
There's also the fighter's Combat Superiority which stops movement altogether.
