I installed vncviewer 0.61 on n800 and ultravnc 1.0.4rc14 on my xp and vista boxes. vncviewer connected to xp box perfectly. Although it can connect to the vista box, it disconnected itself whenever the first action - typing a key or moving the mouse - happened. I checked the winvnc.log. it appeared nothing was wrong and showed that the viewer asked the disconnection. Any insight?
