I am trying to get the proceed to paypal button to open in a new window. My site is Joomla Based with the cart in an iframe to preserve the look of my site. Everything works fine until you go to checkout. I have tried both PPS and PPE . anyone have any suggestions?

the answer was in (your_shop) /ccdata/datagoppwps.inc.php

<div class="paypal_feedback">
<a href="http://www.paypal.com" target="_blank"><img src="ccdata/images/PPLogo.png" align="right" border="0"></a>
<h3>Proceed to secure credit card checkout with PayPal</h3>
<p>Thank you for shopping with us!</p>
<p>We will now transfer you to the secure payment gateway where you can enter your credit card data.</p>
<br/><br/>
<form style="display:inline;" action="<?php echo $myPage->getUrl('cancel'); ?>" method="POST">
<input type="submit" name="return" value="Return to the Shop" />
</form>&nbsp;&nbsp;&nbsp;
<form style="display:inline;" action="<?php echo $myPage->getConfigS('PayPalWPS', 'URL'); ?>" method="POST">
<?php echo $checkout->getCheckoutFields() ?>
<input type="submit" name="_xclick" value="Proceed to Checkout" />
</form>
</div>

target=blank will give users a blank paypal login page. We need to use the target=parent so that your shopping cart shows up
