I am using property nodes on image display to set the position center ( X and Y ) and the zoom (X and Y). When using only position center property nodes everything works fine , but if i set the zoom value with property nodes the position center doesn't work any more, the image stays in the default position. Is there any known reason for this behavior? I am using Laview 7 under windows 2000 professionnel, and i am acquiring an image with a PCI 1408 card. Thanks,
