Hello again

I have almost finished my personalizations. But, have found a couple more sticking points.

I have adjusted the drop down menu so that the buttons are evenly spread across the Drop Menu, and each drop-down list is the same width as the parent. But, now there seems to be a space between the parent and child, enough to close the menu unless I am super quick. I used to know this stuff from years ago when the flyout menu contribution was still quite new, but I can't remember what to look for and none of my fiddling is fixing the problem.

Code:
body {  
	behavior: url(includes/csshover.htc);
	}
	

/*grey*/ 
div#dropMenu li a:hover, div#dropMenu li.submenu li.submenu:hover, div#dropMenu ul.level2 a:hover {color: #4f4f4f!important;background:#D5D5D5;}

	
#dropMenuWrapper {
	width:100%;
	height:2.17em;
	margin:0;
	font-size:1em;
	}
	
div#dropMenu {
  	width:70em;
  	margin:0 auto;
    text-align:center;
	z-index:1000;
	position:relative;
	}

div#dropMenu ul {
	margin: 0; 
	padding: 0;

div#dropMenu li {
