I am using DNN 4.3 and am having a strange menu problem. I have styled my menu and sub menu, they look great but once I roll over them and then roll over thier parent link, they all get a top and bottom border with the color #444444. I have border="0" on .MainMenu_MenuItem and .MainMenu_MenuItemSel. Ther is no mention of #444444 on any style sheet. I have styled a similiar menu using the exact same technique with DNN 3.2.2 and did not have this problem and was wondering if this could be a problem with this new version.

Here's a picture of my problem (I have only rolled over down to Newsletters):




Also, I have styled .MainMenu_Idle with border-top: 4px solid #5a5a5a; Works fine in Firefox but won't show up in IE. Any ideas?

Here is my CSS for the navigation:


div#nav
{
    position : absolute;
    right: 0;
    top: 42px;
    _top: 22px;
    width : 515px;
    font: bold 11px tahoma, verdana, sans-serif;
    color: #5a5a5a;   
}
/*-- box that holds the menu --*/
.MainMenu_MenuContainer {
    background-color: transparent;
    width: 100%;
}


/*-- bar that holds the menu? --*/
.MainMenu_MenuBar {
    cursor: pointer;
    cursor: hand;
    background: #fff;
    width: 100%;
}
/*-- applies to items in submenus only --*/
.MainMenu_MenuItem {
    font: bold 10px verdana, tahoma, sans-serif;
    color: #5a5a5a;
    background: #fff;
    padding: 2px 8px 2px 2px;
    border: 0px;
}

/*-- hover state in submenus only --*/
.MainMenu_MenuItemSel {
    font: bold 10px verdana, tahoma, sans-serif;
    cursor: pointer;
    cursor: hand;
    color: #be0033;
    background: #ffffff;
    padding: 2px 8px 2px 2px;
    border: 0px;
}

/*-- submenu container --*/
.MainMenu_SubMenu {
    font: bold 10px verdana, tahoma, sans-serif;
    z-index: 1000;
    cursor: pointer;
    cursor: hand;
    background: #fff;
    padding: 1px;
    border: 1px solid #5a5a5a;
    border-top: none;
    filter: none;
}

/*-- idle state for root menu items --*/
.MainMenu_Idle {
    cursor: pointer;
    cursor: hand;
    color: #5a5a5a;
    font-family: Tahoma, Arial, Helvetica;
    font-size: 9pt;
    font-weight: bold;
    font-style: normal;

/*-- hover state for root menu items --*/
.MainMenu_Selected {
    cursor: pointer;
    cursor: hand;
    color: #be0033;
    font-family: Tahoma, Arial, Helvetica;
    font-size: 9pt;
    font-weight: bold;

    border-right: 1px solid #5a5a5a;
    border-top: 4px solid #be0033;
    background: #fbfbfb;
    display: block;
    padding: 6px 0 0 0;
    width: 102px;
    text-align: center;
}

/*-- applies to the active root menu item --*/
.MainMenu_Active, .MainMenu_BreadcrumbActive {
}

.MainMenu_RootMenuArrow {
}

#nav table td td { text-align: center; width: 102px; padding: 0;}

/*-- stuff we don't need to see --*/
.MainMenu_MenuArrow, .MainMenu_MenuBreak, .MainMenu_MenuIcon  {
    display: none;
}

#tddnn_dnnSOLPARTMENU_ctldnnSOLPARTMENU36
{
     display: none;
