the old forum server http://forum.ultravnc.info/viewtopic.php?t=2830 had a suggestion of how to do this auto scroll.
I am not sure where / which files to place this in the latest source i downloaded, if anybody can help out. thanks
I usually remote into multiple screens or huge screens sizes, and its a real pain even with my 24 " since my remote computers have 32 inches screens.
i don't like the fixed/scale because you can't read the fonts then or just looks blurry.
