Странно, практически ничего не поменял, но всё работает.)

<script type="text/javascript">
	function mybut(elId, flag) {
	     if (typeof flag == 'undefined') {flag = 0};
	     var elem = document.getElementById(elId).style;
		 var elem2 = document.getElementById('event');
	     switch (flag) {
	          case 0: elem2.innerHTML+='0 | '; break;
	          case 1: elem2.innerHTML+='1 | ';  break;
	          case 2: elem2.innerHTML+='2 | ';
	     }
	}
</script>
<div style="width:336px;height:76px;background-image:url('/forum/images/ca_serenity/misc/logo.gif')"  id="but1" onmouseover="mybut('but1', 1)"  onmouseout="mybut('but1')" onmousedown="mybut('but1', 2)"  onmouseup="mybut('but1', 1)"></div>
<div id='event'>События:</div>
