Express defaulting to "Create a PayPal account"

Whenever a customer chooses to check out with paypal from the the Shopping Cart button the resulting Paypal page is showing the option "Create a PayPal account" with the "Have a PayPal account?" minimised.

On other stores I've tested and used the default is usually to have "Have a PayPal account?" expanded, with a pre-populated email entry with the last paypal email used on that computer. Which would seem to be good from a user experience perspective.

I've looked through the Profile settings in Paypal and can't find anywhere to alter that behaviour, so wondering if there is something on the zencart side that could be configured to match this behaviour ie expanding the Have a PayPal account option in the same way as other stores/ebay.

If anyone stumbles on this thread I found a solution, which tests out OK, the change was on the following line in includes/modules/payment/paypalwpp.php, the change is highlighted in red

$options['LANDINGPAGE'] = 'Login';  // "Billing" or "Login" selects the style of landing page on PayPal site during checkout

Perhaps this can be configurable in a future release?
