Hello Bojan, Thank you for contacting National Instruments.
You seem to be having a problem with multiple instances of the Time Delay Express VI appearing in the VI hierarchy. I was not able to reproduce the same behavior here on my system using the instructions you provided. After looking at your image002.gif, it seems that you have multiple copies of the Time Delay Express VI (located in /LabVIEW 7.0/vi.lib/express/express execution control) opened, since each one appears as a top level VI in the hierarchy. If you open a blank VI and place a Time Delay Express VI in a For loop, you will notice that it does not place multiple instances of the express VI in the hierarchy. I hope this solves your problem. If you have any further questions, let me know. Matthew C Applications Engineer National Instruments
