I have a flash form (CS3 AS2) which has login and register sections. I've tested it in IE, FF and Safari and it works in all of them.

However, my client gets a few emails a week saying it doesn't work. I've talked with someone who couldn't get it to work and she said she used Safari 4.0 and that the submit button didn't do anything. This is the same version of Safari I have and it works fine for me. If it was one person having problems it would most likely be their fault, but quite a few people have complained now. I don't know what it could be. Any ideas?
