Flash Script to make window flash if not in focus?

programming flash
1

Like my last thread, I have created an IM for my website and I am just wanting to add a few more things to it. Now I am trying to have the window flash when a new message is received. I am currently trying to use the code below, but it is not working :


if(messageIn.newmessage == 1){
  getURL('window.setTimeout("window.focus();", 5000);');
}

I only want the window to flash if the current window is not in focus. Kind of like Yahoo IM and MSN IM’s when you have it minimized and you get a new message.
