There is one particular window which I just can't open. Can on the other 3 computers on the network but it just sort of blinks when I press the 'next' button and stays where it is. No error messages at all and no other websites shee to do this. I'm on the registration page of a club and it won't take me past the first page. As I need to do the registrations of a whole team, it is important that I can do it on my computer.
