In my VI when it starts it sends couple of commands to the hardwar using write GPIB.  The whole VI is working perfectly while tested as a VI in labview. I have created now a stand-alone executable  and the the GPIB write command stopped working when my executable boots up. What did I do wrong?
The code can be seen here. http://forums.ni.com/ni/board/message?board.id=170&message.id=332568#M332568
The  first GPIB write thad does not seem to work in executable can be found in the first frame of the sequance in the SPEKTR.vi.

I have figured it out myself. The cause was trivial race condition. It is interesting though that the race condition never appeared in the VI until I compiled it into an executable.
