When I tried to purchase something on an online store via paypal, it will open a new protected browser page (green box one) to do the transaction in paypal account but after that it will not return to previous checkout page or finalization page of the merchant site. Yet, my bank will send me a massage that a payment is done in paypal immediately. However, there is no transaction record on paypal or order placed in merchant site. Luckily, I asked the bank and they said the transaction was cancelled. I tried to place the order and confirm the paypal in the same protected browser, it worked perfectly. Tried to reset the chrome and KPS software, problem still exists when there are two browser (standard and protected) involved during online transaction. I think it is the issue that protected browser has no input back to original standard merchant site.
