function ShowMenu(bMenu) {
document.all.idFinder.style.display = (bMenu) ? "none" : "block" 
document.all.idMenu.style.display = (bMenu) ? "block" : "none"
idML.className = (bMenu) ? "cOn" : "cOff"
idRL.className = (bMenu) ? "cOff" : "cOn"
return false
}
</script>

<style>

</style>
<script>

</script>

<style>
    #board {cursor: default}    
    #board TD {width: 25px; height: 25px; }
  </style>

加入如下代码到body区域

<script>
    var size=10
