Address Information popup shows only halfway

When the user starts to checkout, on some displays the address pop up doesn't show fully. Is there something I can do to correct this?

Could you give us a link to your website ?

I've sent you a message with the link & password

It's working fine for me, could you give us more details on when it happens ?

On which browser, after which action ?

It happens on firefox or chrome (the only two browsers I'm using)
it happens when a user adds an item to the cart and it takes them to the checkout area - but only if they are putting an address in for the first time (meaning that the address fields are empty to begin with).

Also, I've enabled new user registration - so you can make a new user and test it out that way.

As you can see on this screenshot there is no problems on my end.
I tried on Firefox, with not registrated user, first time I enter the address.

Thank you for looking into this. I don't know how it fixed itself, but perhaps adding that second line forces the browser into showing the whole popup. Strange, but I'm glad it's working!
