Change Link under "continue shopping" or disable it

[tamerg]

anyone can give me a hint where and how to change the link under continue shopping??

or in other words: in the facebox popup i just want that the popup closes when clicked on continue shopping.

in checkout i get the error, that the link under continue shopping leads to the same page (just refreshes checkout) (i think that happens because Im using k2mart, and I am not coming from a virtuemart page)

thx in advance
