Spry menu hover: How to get rid of white box with "false"?

Question

Hi--
I'm encountering an IE issue with a Spry vertical menu bar. When the user hovers over the submenu, white frames appear behind the submenu with the word "false" in them. Of course this doesn't happen in Safari or Firefox.
I was able to fix other similar problems with the menu by following tips posted on another forum. Namely, in the CSS, I disabled an IE hack that caused a white background to appear (menu background has to be transparent on this site). And in the JS, I disabled the following: this.removeIframeLayer(menu);
Here's the URL: http://www.qic-ec.org
Below are the css (1) and js (2).
Any help would be DEEPLY appreciated.
Thank you
Jackie

SpryMenuBar.js
This file handles the JavaScript for Spry Menu Bar.  You should have no need
to edit this file.  Some highlights of the MenuBar object is that timers are
used to keep submenus from showing up until the user has hovered over the parent
menu item for some time, as well as a timer for when they leave a submenu to keep
showing that submenu until the timer fires.

Do you have any suggestions for how to adjust the JS so that the menu functions properly in IE? As I said, I upgraded to Spry 1.6.1 and uploaded the new CSS and JS and the problem is still there. The CSS is the same as in the previous version. The new JS is:
