Siege problem

Hi guys ! Well i have a siege problem... In my Mac campaing i own Segestica and the Romans were bringing one stack after the other so when the siege started in their turn i attacked them in mine i won the battles and so far so good But recently when a roman stack is sieging the town and i attack them the mouse cursor is A spining hour glass and the battle doesn't start note the game doesn't freeze you can move around the map but slower than normal... Any ideas ?

Have you tried to press space to get the animations to go faster? I've occasionally got past armies or agents not moving this way. Also, you could try to move a unit out of any city and back in before starting the sally, that seems to reset some stuff concerning character movement.

Ok thanx i'll try this ...!
