Vituemart Check Out Pop Up Box Wrong Size in K2

Hi there,

when i am viewing a virtuemart product in k2 and then add it to cart, the following pop box is the wrong size and the layout is wrong.

i have tried to change the size in the public_html/components/com_virtuemart/themes/default/theme.js but to no affect.

the layout is fine if you add to cart within virtuemart itself - the problem only happens when you add to cart from K2

thanks
Alex
