Changing the title of a form

I had posted a question in another category asking if there was a way to change the title of a form.  After not hearing anything I came up with this.  It's risky because a very simple change on NetSuite's part would break it but it does the trick...

function OnPageInit()  {      try      {                  SetFormTitle('New Title');      }      catch(err)      {          HandleClientScriptException(err);      }  }    function SetFormTitle(title)  {      //  get all the <td> elements and search for one that is using      //  class = 'tasktitlemed' - this is our guy!      //      //  Code like this in an environment like NetSuite is always at      //  risk of being broken and will... it's just a matter of when.      var cells = document.getElementsByTagName('TD');      if(cells != null && cells.length > 0)      {          for(var i = 0; i < cells.length; i++)          {              if(cells[i].className == 'tasktitlemed')              {                  cells[i].innerHTML = title;                  return true;              }          }                    throw 'Failed finding title
