Window. showModalDialog - Unable to "hold" the child window

Hi!
I have 2 ascx pages coded for sharepoint.

1: There is a hyper link that when clicked, will launch a new window via javascript: showModalDialog.

2: The ascx page that the new window is shown. There are just some buttons etc to save back to database.

Problem:
When the hyperlink is clicked, the window appears. I then click on the button to save and attempt to close the window using window.close. But this is happening way too fast for my button to process some stuff before closing.

I've tried to use a while loop, do loop, but currently i am using a for loop... Looks a bit stupid... but i've totally no idea how to "slow" down the javascript... Any advice?

//Code for part 1:
function openChildWindowCustodian(input){
  var myWidth = 0, myHeight = 0;
  var NewWidth = 0, NewHeight = 0;
  if( typeof( window.innerWidth ) == 'number' ) {
    //Non-IE
    myWidth = window.innerWidth;
    myHeight = window.innerHeight;
  } else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
    //IE 6+ in 'standards compliant mode'
    myWidth = document.documentElement.clientWidth;
    myHeight = document.documentElement.clientHeight;
  } else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
    //IE 4 compatible
    myWidth = document.body.clientWidth;
    myHeight = document.body.clientHeight;
  }
  
  NewWidth = Math.round(0.8*myWidth);
  NewHeight = Math.round(0.8*myHeight);
  window.showModalDialog('../../AccessControlASPX.aspx?myKey='+input,'','dialogHeight='+NewHeight+'px;dialogWidth='+NewWidth+'px;scroll=yes;center=yes;');
  }
 
 
 
 
 
//Codes of the 2nd page. When the button is clicked, it will invoke this javascript.
function saveandclose(){
         //var t=setTimeout("",2000); -> Does not work 
 
//This is for the button to be clicked. Note that button2 is hosting all the backend codes to be executed.
        var dd = document.getElementById("<%=Button2.ClientID%>");
        if (dd){
            dd.click();
        }
        
 
//Attempt 2: Tried to set the textcheck textbox value to 1 under the button2. so that it can "stay" in here for a while... dont work...
        var checktext = document.getElementById("<%=TextCheck.ClientID%>");
        do{
            checktext = document.getElementById("<%=TextCheck.ClientID%>");
        } while(checktext == null);
 
 
//Currently using this, works about 50 percent of the time...        
        for(var i=0; i < 1000000; i++){
        }
        
//Attempt to close the window and return to parent.
        closeWindows();
        }
