I've create a web part that displays a SPGridView with an SPMenuTemplate. My problem is the context menu that pops up has these little arrows on the left hand side which are undesired and which also throw the other items out of kilter. DOes nyone know how to gget rid of them?

My menu template code is:
<SharePoint:MenuTemplate runat="server" ID="classifiedsTitleTemplateID">
<SharePoint:MenuItemTemplate ID="ViewClassifiedItemTemplate" runat="server" Text="View Item" ClientOnClickScript="classsifiedsPostBack('View,%Title%');" />
<SharePoint:MenuItemTemplate ID="EditClassifiedItemTemplate" runat="server" Text="Edit Item" ImageUrl="/_layouts/images/Edit.gif" ClientOnClickScript="classsifiedsPostBack('Edit,%Title%');" />
</SharePoint:MenuTemplate>
