"Access is denied" issue in scripting

I have started to see this issue as well using IE9.   See function CloseIE below.

I ichanged the code from Sys.Process... Close() to Sys.Process...Terminate() to avoid having to deal with the are you sure you want to leave popup.



However, I now get access denied referencing the .Terminate()  line.



NOTE:   When I tried to use this routine



function trial43014a() {

    Sys.Process(browserToUse).Terminate();

    Sys.Process(browserToUse).Terminate();



}



I never got "access is denied" .  I just got  the process was not found.



function CloseIE()

{

    //Try timeOutWait times to close IE

    var count = 0;

  while(Sys.WaitProcess(browserToUse, 0).Exists)

//  while (Sys.WaitProcess(browserToUse, 1500, 1).Exists)

  {

//Sys.Refresh();// Sys.Process("iexplore').Close() 7.13.2012

    

// 4/29/14  previously was .Close() stopping due to "are you sure you want to leave" popup  use .Terminate()

    Sys.Process(browserToUse).Terminate();

    Sys.Refresh();

    //while(Sys.WaitProcess(browserToUse, 1000).Exists){}

    

    // I've seen an infinite loop when this is called and a modal popup "are you sure you want to leave"

    // when in GMAIL occurs...  Curt H. 6.22.2012

      if (count > 9) {

        Log.Error("Attempted to close browser more than 9 times ");

        Sys.Process(browserToUse).Terminate();

        throw new Error("excessive Browser closures" );

     }

     count++;



  }

}
