I am using LabVIEW 8.2 version(professional) in company, and 8.5 evaluation at my home. The peoblrm is, feedback node is not works in company without while or for loop. But in 8.5 evaluation it works even without any loop. Is there any solution for my problem!!!!! shall do any updates(not upgrade!!) in 8.2 to get feedback node worked without loops.
