I have no idea how to search out a previous solution for this.
I had one customer order a product. ten minutes later, another customer contacted me stating that the previous customer's name and other relevant data was pre-populating all of the fields on his order. This was verified. he stated closed the window.
I asked him to retry with a fresh browser open. No problems occured then.
User data being transfered from one customer to another? had anyone heard of this already?
