That's odd, you should be able to see a little little javascript icon next to the menu (in 'design view'). Never nind, i- go to code view, and place your cursor inside the menuwriter javascript code block, which looks a bit like this:
<script type="text/javascript">if(window.attachEvent) { window.attachEvent("onload", function() { cssmw.intializeMenu('cssmw',{select_current: 0, orientation: 1}); }); } else if(window.addEventListener) { window.addEventListener("load", function() { cssmw.intializeMenu('cssmw',{select_current: 0, orientation: 1}); }, true); }</script>
The edit buttons should now show up in the properties panel.
Sorry to be long in replying, - the town's power supply went off as I was about to post back.
