Rather then trying to disable mouse actions, try disabling script
actions...

For example, set a Global variable when the request is sent to the
server

  xmlhttp=new XMLHttpRequest()
  xmlhttp.onreadystatechange=xmlhttpChange
  xmlhttp.open("GET",url,true)
  xmlhttp.send(null)

  Processing = true; //now we know that we are waiting for a response

then in the stateChange function (the current request was completed)...

function xmlhttpChange() {
if (xmlhttp.readyState==4) {
  if (xmlhttp.status==200) {
       Processing = false;//now we know we've had a successful response
    }
}

now before execution of any other function code, wrap a
function OtherPageAction() {
   if (!Processing) {

//do other page actions like normal

   } else {
      UpdateSomeUserMessage("Processing... Please Wait");
   }
}

This would obviously need to be tailored to your script, but I hope the
concept helps.
