[Flash8] .send and getURL open two windows!

Hi everyone,
I really hope you can help me with this.
I have a Flash form sending variables to an ASP script (bono.asp) in order to print a discount bonus. The bonus grafic is then shown in a new window for the user to print with his/her data on it. (name, address, etc).

Well, the problem is that it not only opens a new window with the bonus (without the data ), it also opens the bonus in the current window (with the data), forcing the user to “go back” to the flash website and loading the entire animation again.

This is the code in the Flash form asociated to the Button:

on (release){
variables = new LoadVars();
variables.nomclub=nombreclub.text
variables.cedclub=cedulaclub.text
variables.telclub=telefoclub.text
variables.mailclub=emailclub.text

    //send variables to basedatos.asp, to put data in the company DB
    variables.send("basedatos.asp", "", "POST");
    
    //send variables to bono.asp, to show the bonus with the data
variables.send("bono.asp", "", "POST");

   	var targetUrl:String = "bono.asp";
    getURL(targetUrl, "_blank");

} 

In the ASP file (bono.asp) all I do is Request the variables and put them in the proper place.

Hope you can help me, thank you in advance
