The ideal solution is to use SkipLinkText attribute in asp:menu, and you have to let it blank. Example :
<asp:Menu
ID="Menu1"
runat="server"
DataSourceID="SiteMapDataSource1"
DynamicHorizontalOffset="2"
Font-Names="Verdana"
Font-Size="0.8em"
ForeColor="#284E98"
StaticSubMenuIndent="10px"
Width="180px"
SkipLinkText="">
If you use SkipLinkText empty, ther wiil not be 1 pixel hidden image or hidden link.
