Betfair On Nokia X6 - Arggghhh!!!

Can anyone help me please?

I'm trying to open Betfair mobile on my Nokia X6 and it's giving me such a small screen to try and enter my user name and password into.

It shows me the two boxes and then the tiniest qwerty keyboard.  Also there is a big circle with four directional arrows on it but they only take me to the starts and ends of the boxes.

Anyone have the same problems and overcome them?

This is in portrait mode too by the way

Thanks

Ian
