The horizontal drop menu background height expands sporadically in Firefox. When you go to another page and click on the same drop menu again it works fine. This is very annoying. Do you have a fix for this? The web test site is: www.piercevision.com/new2

Hello,
You made some changes to:
www.piercevision.com/new2/Styles/dmxNavigationMenu.css

.dmxNavigationMenu ul.horizontal {
	float: left;
	margin: 100;
}

This margin:100 is causing the issue + it is absolutely wrong. 100 is not a proper value. 100em or 100px or 100% or ?

Thank you for finding the problem for me so quickly.
