My css inline submenu won't stay open long enough to select an option. As soon as the cursor leaves the main selection the submenu box closes. Can be viewed at: http://isite.thevatraininginstitute.com/home.htm

'#ao_nav li {}', this statement overwrite '#ao_nav li#contrast{}', and '#ao_nav li#first'. If you need more than one selectors with same properties, group these selectors:

#ao_nav li#contrast, #ao_nav li#first {
			display:inline;
			margin:3px 0 0 10px;
			position:relative;
			float:left;			
			height: 20px;
			color: white;
		    font-size: 9pt;
		    font-weight:bold;
}
/* this is the same because the '#first' and '#contract' are the children of ul container which is under '#ao_nav' div */
#ao_nav ul li{
			display:inline;
			margin:3px 0 0 10px;
			position:relative;
			float:left;			
			height: 20px;
			color: white;
		    font-size: 9pt;
		    font-weight:bold;	
}

Instead of:

#ao_nav li#first{
			display:inline;
			margin:3px 0 0 10px;
			position:relative;
			float:left;
			height: 20px;
			color: white;
		    font-size: 9pt;
		    font-weight:bold;
}
#ao_nav li#contrast{
			display:inline;
			margin:3px 0 0 10px;
			position:relative;
			float:left;			
			height: 20px;
			color: white;
		    font-size: 9pt;
		    font-weight:bold;	
}

The 'text-align:bottom' was not right. 'text-align' has three values 'left,right,center'.
The sub menu cannot be show longer because it's parent 'li#first' has '20px' height, and it positioned at '30px' top from it's parent. Replace 'top: 30px' with 'top: 20px' in '#ao_nav li ul' properties. It would be work. Good luck..
