Can not call Swap.AllInstances() more than once on a type.

Hi - we are having some issues with the following test method;

[TestMethod]
[Isolated]
public void TestSynchroniseFullSyncTrigger()
{
SynchronisationService synchronisationService = Isolate.Fake.Instance<SynchronisationService>(Members.CallOriginal, ConstructorWillBe.Ignored);
Isolate.WhenCalled(() => ConfigurationManager.AppSettings["FullSynchronisationIntervalInSeconds"]).WillReturn("100");
IConnectionMonitorService connectionMonitorService = Isolate.Fake.Instance<IConnectionMonitorService>();
Isolate.Swap.AllInstances<IConnectionMonitorService>().With(connectionMonitorService);
Isolate.WhenCalled(() => connectionMonitorService.IsConnected()).WillReturn(false);
bool eventCalled = false;
synchronisationService.CaseHeaderListUpdated +=
delegate(object sender, EventArgs e)
{
eventCalled = true;
};
synchronisationService.Synchronise(false);
Assert.IsTrue(eventCalled == false);
}


When calling the line;

Isolate.Swap.AllInstances<IConnectionMonitorService>().With(connectionMonitorService);

We get the following exception;

Test method ***.Synchronisation.Test.SynchronisationServiceTests.TestSynchroniseFullSyncTrigger threw exception: TypeMock.TypeMockException:
*** Can not call Swap.AllInstances() more than once on a type.

Note we have used the [Isolated] attribute on both the Test Class and Test Method.
