And this is the actual link that displays the menu when you mouseover:
<li><a href="http://www.scilogs.de/" class="start" onMouseover="dropdownmenu(this, event, menu0, '')" onMouseout="delayhidemenu()"><em>SciLogs</em></a></li>
2. you're changing it in the wrong place - the global section sets the default template for new blogs only. To change your template (or any other settings) for an existing blog, you go to the "control center", to the left of the administration tab.
