Hey folks!
I've got the same problem but it only happens with multi-item orders. It took me forever to figure out it wasn't my site - but PAYPAL that is causing the problem. I contacted their customer service department and the guy I talked to really didn't seem to have the first clue what I was talking about but he's putting my site "on the list" and said someone will contact me within 24 to 72 hours. If they tell me ANYthing helpful, I'll be sure to post it here. If anyone else comes up with something PLEASE let me know!!!
