PeopleTools v8.55 - 2 Tier Query - Running to Excel - closes on second attempt. Fix in patch release #11

Was curious to see if anyone reading this has picked apart PeopleTools patch #11 to see what the specific fix is to apply to solve to the 2 Tier Query to Excel bug that prevents those on patch release #10 or prior(8.55.10) from running 2 Tier Query results to Excel more than once?
