Window opening behind parent

[IndyChris]

I've got a button my webpage that when clicked will open another
window. Different criteria on the page will deteremine which window
gets opened when the button is clicked. I have a switch statement in my

code and then I set up javascript that I register back to the client.
This is all working fine except for one thing. The window that opens,
opens behind the parent window. I was really hoping that it would open
in front. I believe that the auto postback functionality of the button
is causing this but I'm not 100% sure.

Here's a sample of what I'm trying to do.
switch(this.cal lType.SelectedI tem.ToString(). Trim())
{
case "Meetme":
case "Dialout":
scriptblock += "<script language='JavaS cript'>";
scriptblock += "<!-- \n";
scriptblock += "var winprint=window .open('MeetMe.a spx?sakEvent=" +
SakEvent +"',null,'heigh t=900, width=1000, scrollbars',
'winprint.focus ()', 'return false');\n";
scriptblock += "// -->";
scriptblock += "</script>";
Page.RegisterCl ientScriptBlock ("clientScript" , scriptblock);
break;
case "Q&A":
scriptblock += "<script language='JavaS cript'>";
scriptblock += "<!-- \n";
scriptblock += "var winprint=window .open('QA.aspx? sakEvent=" +
SakEvent +"',null,'heigh t= 900, width=1000,
scrollbars','wi nprint.focus()' , 'return false');\n";
scriptblock += "// -->";
scriptblock += "</script>";
Page.RegisterCl ientScriptBlock ("clientScript" , scriptblock);
break;
case "Roll Call":
scriptblock += "<script language='JavaS cript'>";
scriptblock += "<!-- \n";
scriptblock += "var winprint=window .open('RollCall .aspx?sakEvent= " +
SakEvent +"',null,'heigh t= 400, width=1000,
scrollbars','wi nprint.focus()' , 'return false');\n";
scriptblock += "// -->";
scriptblock += "</script>";
Page.RegisterCl ientScriptBlock ("clientScript" , scriptblock);
break;
case "Recording" :
scriptblock += "<script language='JavaS cript'>";
scriptblock += "<!-- \n";
scriptblock += "var winprint=window .open('Recordin g.aspx?sakEvent =" +
SakEvent +"',null,'heigh t= 400, width=1000,
scrollbars','wi nprint.focus()' , 'return false');\n";
scriptblock += "// -->";
scriptblock += "</script>";
Page.RegisterCl ientScriptBlock ("clientScript" , scriptblock);
break;
}

Can anyone see what I need to add so that my new window will open in
the front>
