Chris, as I found out at the weekend the only way to learn to fly in a cross wind is to fly in one, spent three whole flights just doing stall turns and think I managed to get one (almost) right. The Sim has its uses but is no substitute for the real thing.
I am sure if Jon is at the field on the next windy day he will give you some pointers, after that it's just practice, practice and then practice some more
