<br> Hello Paul, It depends. What version of LabVIEW and what OS are you using?
The first thing I would check is if there are loops in your VI without any delay fucntions in them. This would make the loops run as fast as they can without yielding to other tasks. There can be other causes as well. Is it possible to strip down the VI to a bare minimum where the problem still occurs and post it up here? Regards, <i>Khalid</i><br>
