Can we please have Paypal express become a standard payment method.  I have tried every new release of all the plugins with no solution to this problem.  

Because shipping total is calculated after the Paypal Express button, it does not have a value for shipping so it returns this error.

Please answer if you have a fix.  I have had to resort to sending paypal money requests to every customer.  I have wayy too much time invested into nopcommerce, but if this doesn't get fixed soon i will have much more time invested into sending paypal money requests daily.
