We have TestStand 2013 installed on several workstations. When a single step is selected and executed by right clicking and selecting 'Run Selected Steps' we observe different behavior on some of the machines. For some installations the Setup and Cleanup section will execute and on other machines only the selected step will execute. The same sequence file is being used on all machines.
There must be an option in the Sequence Editor to set this behavior but I have not been able to find it.
