Hello Jeff,
You will need to open the \Operator Interfaces\NI\LV\Execution Display\Execution Display.vi and set a breakpoint at the point of interest. Save this VI with the breakpoint set. Open the file \Operator Interfaces\NI\LV\Sequence Display\Sequence Display.vi and run this. When you open a new sequence file and run it, the breakpoint you set should be hit, providing that code is set to execute.
