no joy with twinvnc just error disconnected.

MorphVNC cmd line gives more info:
MorphOS:Downloads/MorphVNC> MorphVNC 192.168.1.231 raspberry
Readargs failed
MorphOS:Downloads/MorphVNC> MorphVNC 192.168.1.231 pass=raspberry

Connection failed.
Server response: No configured security type is supported by 3.3 VNC Viewer
main.c/main(): RFB_InitializeConnection() failed

I dont know if that means that MorphVNc is too out of date?
