Possible to add spinning wheel?

I've had a lot of people say that nothing happens when they click on "Process payment." Turns out they were just not waiting long enough to be redirected to PayPal.

I changed the text on that page to make it very large and it says "PLEASE WAIT UP TO ONE MINUTE TO BE TRANSFERRED TO PAYPAL," but is it also possible to add a spinning wheel to that page, or something else that indicates the system is working on redirecting them?

Right now, we don't have a way to handle that but I am willing to improve it. Do you have a sample redirection page which you like which you can recommend us to implement?

Regards,

Tuan
