Login and register page gets cutoff

I use a responsive template but when i view the hikashop page where i choose to login or register to complete the order there are problems with it being cutoff from view.

The main component area of hikashop is too wide. the right hand side where it has the register area is half cut off and the recaptcha field is cut off so you cant rotate through them.

i think the login and register need to be one on top of the other and not side by side. maybe make them have a mootools effect where they accordion-slide to save space.

this way the cart will work in ipads and iphones, because at the moment customers cannot complete their order on mobile devices
