Hi All!
I have strange problem with Sandbox (and real acount) IPN responce. When I'm testing it with Sandbox generally payment form shows like this (screen 1):

In that case after payment is done link "Back to the merchant" is a button, and IPN variables successfully sends within POST array. Verification on the site is successful (Screen 2).

But sometimes without any changes in script instead on general payment form is other (Screen 3):

In that case after payment is done link "Back to the merchant" is a LINK (!!!), and after cklicking on it IPN POST array on site is empty and transaction of course can not be verifed (Screen 4).

In real acount about the same whith link: all the way after payment I see the link: "If you are not redirected in 5 seconds, click here." POST array is empty and verification can not be done.
What is wrong?
