Error -18004; An error occurred accessing the LabVIEW Run-Time Engine DLL. TS 4.2.1 / LV 2010

When I try to run a VI that is reentrant in parallel execution, I receive this error.  The details of the error is:  LabVIEW:  The property or method is not supported in this version of LabVIEW.

This is run under the Simple Operator Interface in LV 2010.  The TestStand engine is version 4.2.1 using LV 2010 run-time engine adapter.

If I save for previous version to LV 2009 SP1 and set the TS adapter to 9.0.1 (2009 SP1), this works.

Can anyone reproduce this error (bug?) ?

have you got the latest updates for TestStand using LabVIEW 2010?

Grrr ... installed the TestStand patch but realized I needed to install the LV 2010 f2 patch as well.  I guess it's time to upgrade to TestStand 2010 ...
