What display control are you usng to display your image? That is, on which control is the scrollbar causing problems? Is it a color image? I have done live image aquisition without Vision in the past. I have displayed the image using a picture control and using an intensity graph control. Sounds to me like you are talking about the vi window's scrollbar and your image is in a display control that is larger than the vi window dimensions, or the dimensions of your monitor. Is this is the case?
I am using 6.1, but I may be able to answer your question as long as it isn't 7.0-specific.
