UIMsg_TerminatingExecution (0x5) and UIMsg_TerminatingInteractiveExecution (0x15) can be seen anytime you terminate a sequence while it is executing (via the Terminate button on the OI for instance, or by having a step terminate as part of its
post action).
To catch this message in TS 3.x, create a UIMessage Event callback VI (in LV) like usual and listen for Event equal to 5.
If you're not using LV let me know what you're using and I'll try to match it.
