I need help with adding Drop Down Arrows after every Root Menu Item that has Sub Menu Items in the NAV Menu.

Adding IndicateChildren="true" and IndicateChildImage="<img src='action.gif'>" in the NAV Skin Object does nothing.

Here is my NAV Skin Object:
<dnn:NAV runat="server" id="dnnNAV" ProviderName="DNNMenuNavigationProvider" ControlOrientation="Horizontal" CSSControl="MainMenu_MenuBar" CSSContainerRoot="MainMenu_MenuContainer" CSSContainerSub="MainMenu_SubMenu" CSSNode="MainMenu_MenuItem" CSSNodeHover="MainMenu_MenuItemHover" CSSIcon="MainMenu_MenuIcon" SeparatorHTML="<font color=#c9d7f1>&nbsp;&nbsp;|&nbsp;&nbsp;</font>" IndicateChildren="true" IndicateChildImage="<img src='action.gif'>" />

Here is my NAV CSS:
.MainMenu_MenuBar {background-color: #FFFFFF;}
.MainMenu_MenuContainer {background-color: #FFFFFF;}
.MainMenu_SubMenu {border-top: #eaeaea 1px solid; border-left: #eaeaea 1px solid; border-right: #eaeaea 1px solid; border-bottom: #eaeaea 1px solid; background-color: #FFFFFF; z-index: 1000; filter:progid:DXImageTransform.Microsoft.Shadow(color='#696969', Direction=135, Strength=3); padding: 1px 1px 1px 1px;}
.MainMenu_MenuItem {font-size: 11px; color:#0000FF; text-decoration:none; font-weight:normal;}
.MainMenu_MenuItemHover {font-size: 11px; color:#0000FF; text-decoration:underline; font-weight:normal;}
.MainMenu_MenuIcon {background-color: #FFFFFF; border-bottom: #eaeaea 0px solid; border-left: #eaeaea 0px solid; border-top: #eaeaea 0px solid; border-right: #eaeaea 0px solid;text-align: center; width: 15; height: 21;}

I just had a quick look at the source code & instead of "IndicateChildImage" it has "IndicateChildImageRoot". So if you use the below code it should hopefully work for you :)

IndicateChildImageRoot="/images/help.gif" (change the root menu arrows - works)
