How can I ignore multiple clicks while processing the first one?

Question

Hi -
I am writing my first Flex program so I'm sorry if this is a newbie question.
I have some code which handles a click but takes a while to finish. What I want to do is proces steh first click but ignore any more clicks until the code has finished dealing with the first one.
Can anyone tell me the standard way to do this?
Here's a simplified example with a builtin delay. If I click on the button several times and then wait, the clicks are all processed in sequence and the test count slowly increases. What I want the code to do is ignore any clicks which teh user made during the two second delay but start handling new clicks after the delay has finished.
Example Code...
<<?xml version="1.0"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"
      xmlns:mx="library://ns.adobe.com/flex/mx">
   <fx:Script>
      <![CDATA[
private var count:Number = 0;
private function clickHandler():void {
   // Something which takes a while to complete...
   var timer:Date = new Date();
   while( (new Date()).valueOf() - timer.valueOf() <  2000 ) {
      var nop:int = 0;
   // Report result
   count++;
   output.text="Test Number "+count;  
]]>
   </fx:Script>
   <s:Panel title="Example">
      <s:VGroup left="10" right="10" top="10" bottom="10">
           <s:Label id="output" text=""/>
           <s:Button label="Click Me" click="clickHandler();"/>
      </s:VGroup>
   </s:Panel>
</s:Application>
Thanks

Thanks for the response Pramod. I tried to disable and enable the button but it doesn't seem to have any effect at all. If I click the button several times, this code still processs the clicks one at a time over the next few seconds. I am sure I am making a simple mistake somewhere here...
private function clickHandler():void {
   mybutton.enabled = false;
...slow stuff here
   mybutton.enabled = true;
Full code...
