How to launch additional windows

how to launch second (third, fourth, etc.) windows:

1. login into eu.4game.com with your pa account.
2. start the game.
3. log out from your personal account.
4. login with another account.
5. launch the game.



to start 3 and more windows you need to have active pa at every previous account you had.

you need a separate account for each window.

example 1: launch of the second window - pa+nonpa / pa +pa
example 2: launch of 4 windows - pa+pa+pa+nonpa / pa+pa+pa+pa

 

i'd like to learn how to make a popup window, launched from a button, that allows additional instances of itself to be launched from the resulting popup.
