UltraVNC Viewer

Post by virusbcn »

Hello, when I receive remote assistance requests on my PC, I always have my UltraVNC Viewer open for it to work, but I would like to be able to always have "viewer size set to AUTO" for example, and not have to check it every time I open it, I can't find where I can change this simple change, can you help me?
