What's your exact code?

If I set the following code:

    private void cbDesign_CheckedChanged(object sender, EventArgs e){
        var instance =
    Microsoft.VisualBasic.CompilerServices.NewLateBinding.LateGet(
    wbView.ActiveXInstance,
    null,
    @"Document",
    new object[0],
    null,
    null, null );

         var objArray1 = new object[] { cbDesign.Checked ? @"On" : @"Off" };

    Microsoft.VisualBasic.CompilerServices.NewLateBinding.LateSetComplex(
    instance,
    null,
    @"designMode",
    objArray1,
    null,
    null,
    false,
    true );

The IE9 Web Browser instance enters designMode without any problems. If you change the "Zeta" example to not set the document text after entering design mode, it also works fine.
