Isolate.Verify tells me I didn't fake my instance.

I posted this over at Beginners a few weeks ago, and haven't gotten a reply yet. At this point I'm assuming it's a bug:

(original post: http://forums.typemock.com/viewtopic.php?t=2293)

The codez:

    public class ClassToTest
    {
        public void TestMe()
        {
            var youllBeFaked = new ClassToFake();
            youllBeFaked.VerifyMe();
        }
    }

    public class ClassToFake
    {
        public void VerifyMe()
        {
            throw new Exception("I wasn't faked!");
        }
    }

The test:

    public class TestBase
    {
        protected ClassToFake fake { get; private set; }

        [SetUp]
        public void SetUp()
        {
            MockManager.Init();
            fake = Isolate.Fake.Instance<ClassToFake>();
            Isolate.Swap.AllInstances<ClassToFake>().With(fake);
        }

        [TearDown]
        public void TearDown()
        {
            MockManager.Verify();
            MockManager.ClearAll();
        }
    }
    
    [TestFixture]
    public class ClassToTestTest : TestBase
    {


        /// <summary>
        ///A test for TestMe
        ///</summary>
        [Test]
        public void TestMeTest()
        {
            ClassToTest target = new ClassToTest();
            target.TestMe();
            Isolate.Verify.WasCalledWithAnyArguments(() => fake.VerifyMe());
        }
    }

The exception:
TypeMock.TypeMockException :
*** Isolate.Verify does not support objects that were not faked using Isolate.Fake.Instance(), or passed through WhenCalled()

What am I doing wrong?

Thx for the help.
