Adding a Short Delay before Triggering MouseOver Event

Adding a Short Delay before Triggering MouseOver Event

Dear All
 
I've been using this little bit of code to show a div when the user rolls over a link:
  1. $('a#eventspopupbtn').mouseover(function() {          $('#menu').hide('fast');
  2.       $('#eventspopup').show('fast');
  3.       return false;
  4. });
I have been trying to extend this bit of code so that there is a short delay built in so that if the user rolls over the link by mistake or 'just passing through' the div is not displayed. I tried using setTimeout but couldn't get that working (unfortunately, I can't share that with you because I lost the code).
 
I would really appreciate any help or advice you may be able to share on this.
 
Many thanks
Daniel
