I grabbed this script from dynamicdrive "vertical menu flyout" it works fine in IE but not Mozzilla. It doesn't seem to calulate the x,y position correctly to place the dropmenudiv. It returns the same position from the getposOffset function no matter what menu you are hovering over. For example 192, wher ie gives different values and places the dropmenudiv in the correct location.

here is my HTML:

<ul class="avmenu">
<li><a class="current"  href="index.php">Home</a></li>
			
<li id="menu2" onmouseover="dropdownmenu(this, event, menu2, '165px')" onmouseout="delayhidemenu()"><a  href="education.php">Education</a></li>
			<li id="menu3" onmouseover="dropdownmenu(this, event, menu3, '165px')" onmouseout="delayhidemenu()"><a  href="news.php">News &amp; Calendar</a></li>
<li id="menu4" onmouseover="dropdownmenu(this, event, menu4, '165px')" onmouseout="delayhidemenu()"><a  href="contact.php">Contact</a></li>
<li id="menu5" onmouseover="dropdownmenu(this, event, menu5, '165px')" onmouseout="delayhidemenu()"><a  href="grants.php">Grants</a></li>
<li id="menu6" onmouseover="dropdownmenu(this, event, menu6, '165px')" onmouseout="delayhidemenu()"><a  href="member.php">Member info reports</a></li>
<li id="menu7" onmouseover="dropdownmenu(this, event, menu7, '165px')" onmouseout="delayhidemenu()"><a  href="#">Maine's Health Initiatives</a></li>
		</ul>

Just move the onmouseover and onmouseout event to the <a> tag!
