Our school bought three of these devices and installed the Ladibug 3.0 software on three different laptops. On each laptop, the scaling feature is disabled; all other functions in Ladibug work perfectly. We searched the internet for troubleshooting tips and implemented what we found. We also tried to factory reset Ladibug 3.0. The zoom function still didn't work. We contacted Lumens about the issue and they responded quickly. However, your answer is that the zoom function has been disabled for legal reasons. We've never heard of anything like this. If we had known that, we would never have bought Visualizer. We hope this information is helpful to others looking to purchase a fully functional document camera; it apparently isn't.
