Can't Mock through a property

OK - I found the problem. I just would like to know why it caused me so much heart-ache. This code compiles but it will not run - the Exception caused me a lot of grief also - italicized below. As soon as I change the FakeAnother property to a member instead of a property, everything works happily.

TypeMock.TypeMockException occurred
Message=" *** No method with name Setup>b__1 in type GenericBaseClassTest exists."

It looks like the "Setup>b__1 in type GenericBaseClassTest" has overwritten the real missing method name.
