We have now taken receipt of this item and I must admit to having spent a number of very frustrating and non-productive hours trying to get acceptable results from it. We first installed it on a machine running Vista and despite downloading the latest drivers, we were unable to get the machine to function. I next installed it on a machine running Windows XP. We downloaded the latest drivers and started to use it. Every Negative that is scanned produces what can only be described as a Zebra effect photo on the screen accompanied by either a total Green, Blue or Red hue. is this a setting we need to adjust or is the scanner broken? any ideas would be appreciated?
