i have added the add to cart button, it takes my customers to the paypal shopping cart but when the customer clicks continue shopping it informs them to open a new browser window. thats just not approiate, it should return them to the last page they were on or atleast to my home page.
When your customer does click on the Add to Cart button and then continue shopping it should return them to the page they were shopping on unless the code reads target="_blank" for the page it will be redirected to. I hope this helps.
