I want to use VNC from XP to my Mac OSX 10.5.8. I have enabled "Screen Sharing" and it says "Screen Sharing: On". It also says to use vnc://192.168.0.15". So I downloaded the latest VNC and ran the VNC Viewer on my XP computer. It connects then asks for the password. But then it just blinks on/off a window as if the viewer is terminating immediately. Does anyone know what could be going wrong?
