DNN User Registration Fix

I'm having a "width" problem with the User Registration module. When you try register stretches out wide. But if i login as an Admin or Host, with the exact same fields appearing it doesn't stretch out. [login to view URL] I've been testing by modifying the [login to view URL] file and I'm pretty sure something to do with the <asp:panel id="pnlTabs" runat="server" > tag. DNN 5.5.0
