against blank block blockers cart checkout clients customization dismayed dismissed documented google help intact leaving open original page payment paypal pop-up processor processors site strongly times window

Is it possible to have paypal or google or whatever open in a blank page on checkout. Clients I have are dismayed that the site is dismissed by the payment processors page. They would rather have the processor open in its own window leaving the original site intact.

Although it's very much possible and is documented in "cart customization" section of our help page, I'll strongly advice against it as pop-up blockers will block the new window most of the times.
