override and internal

In a base class, a method is declared protected internal virtual object
SaveViewState();

I can override it protected virtual object SaveViewState(); but I can not
add the internal keyword. Why not?

Compiles fine, on .NET 2.0 VS2005

class A {
   protected internal virtual object SaveViewState()
   {
       return null;
    }

}

class B : A {
    protected internal override object SaveViewState()
    {
        return base.SaveViewState();
    }
}

That's wierd. I get the following error:

Error 1 'Custom.Web.UI.WebControls.MyStyle.SaveViewState()': cannot change
access modifiers when overriding 'protected' inherited member
'System.Web.UI.WebControls.Style.SaveViewState()' C:\Develop\2.0\Class
Libraries\Web.UI.WebControls\MyTest\MyStyle.cs 32 48
Custom.Web.UI.WebControls.MyStyle

public class MyStyle : Style
{
    public MyStyle(): base()
    {
    }

    public MyStyle(StateBag bag) : base(bag)
    {
    }

    protected internal override object SaveViewState()
    {
        return base.SaveViewState();
    }
}
