Flyout Menu hidden in IE

[p9142]

I am using UDM menus for the first time, and the flyout menu keeps getting hidden by things in my main content section of the page. Everything works fine in Firefox and Safari, but in IE it gets hidden. Here is the address to the page where I am having trouble. http://www.wiu.edu/users/ppc102/menu1/

My udm-custom.js has the z order set to "1000"

um.orientation = [
	"vertical",	// alignment ["vertical"|"horizontal"|"popup"|"expanding"]
	"left",		// h align ["left"|"right"]
	"top",		// v align ["top"|"bottom"]
	"absolute",	// positioning ["relative"|"absolute"|"fixed"|"allfixed"]
	"0.5em",	// x position ["em"|"ex"|"px"|"0"]
	"0.5em",	// y position ["em"|"ex"|"px"|"0"]
	"1000",		// z order ["0" to "10000"] (menu takes 20000 headroom)
	];
