Thank you Krileon.

Right now, we've setup a Paypal payment gateway using the sandbox server.

After making the payment on the Paypal website, there is a button to click to return us back to our site and I'm pretty sure we've configured things properly and have also entered a return url on the sandbox account and we're also using the merchant ID, identity token, api credentials, and email of the "sandbox" account.

For some reason, after clicking the button to return back to our website, it always seems to take a long time, like over a minute.

Any ideas on how to resolve this would be greatly appreciated.

Thanks in advance,
V
