Actually, looking at your source, you're talking about Anylink menu, not anylink CSS menu. Got me quite confused for a while. 
The problem should be simple to fix. Right now you're entering in an incorrect value for each of the drop down menu's width when calling dropdownmenu(), for example:
Code:
<a class="topnav3" style="cursor:default;" href="#" onClick="return clickreturnvalue()" onMouseover="dropdownmenu(this, event, menu4, '110px')" onMouseout="delayhidemenu()">
HEALTH TECHNOLOGY</a>
Change the part in red for all four links to the correct menu width, for example, 330.
