multiple notification in Paypal standard method payment

[motybz]

why i got a lot of notification of "payment confirmed"? i tried to change the status to "shipped" but how often status changes itself back to "Payment Confirmed"...
how can i fix it?

would appear the Paypal IPN is being resent multiple times - you can check your server access logs to see if this is happening

The problem is with Paypal or with virtuemart?
