    Reviewing 1.0.9.6.2 (Feb 20, 2012)

    not a bad remote VNC but not for the novice. Team-viewer has my top pick for it's simplicity.

    Reviewing 1.0.9.1 (Nov 8, 2010)

    Can download @ http://www.uvnc.com:8080...c/90-ultravnc-1091.html

    ChangeLog:

    Server + Viewer:

    Integrated support for SecureVNC plugin.
    Fix recursive clipboard issues when several VNC, RDP, VM, etc sessions are nested.
    Fix hangs in clipboard handling.
    Support for HTML and RTF clipboard formats.
    Support for Unicode clipboard text.
    Clipboard text is compressed when transferring.
    libjpeg library replaced with libjpeg-turbo which includes optimized assembly code for both x86 and x64.
    Zlib updated to latest version.
    DSM plugins no longer cause the server/viewer to send any additional messages or prefix bytes. This eliminates 41 bytes of network traffic per message.
    Immediately subsequent socket writes are coalesced to minimize unnecessary packets. This eliminates 40 bytes of network overhead for most messages, and more in other cases.
    RFB 3.8

    Viewer only:

    Fix crash when changing framebuffer dimensions with cache encoding enabled.
    Fix disconnect when changing framebuffer dimensions.
    Some menu reorganization.
    Throttling for mouse move messages to prevent saturating output buffer with pointer updates.
    Queueing implemented for outgoing writes; this eliminates some overhead from every message.
    Preemptive update requests.
    Enable cache encoding from commandline, /enablecache
    Fixed stability issue in Tight encoding (merged from TightVNC)
    Fixed recovery / resynchronization attempts in update handler due to bypassing DSM plugin when flushing input buffer, leading to unsynchronized encryption states.

    known limitation 1.0.8.2 built 7 december 2009

    * FT transfer folder to top level of local or remote drive C is not possible if winvnc running as service system, even your are computer administrator between vista/7
    user Prisma solution:
    winvnc/vncviewer write temporary files into the %Temp%-directory.

    * uvnc_settings.exe (Start... Programs... UltraVNC...Edit Settings)
    on vista/7, require run as administrator even you are computer administrator.

    * vncviewer autoreconnect commandline blocked on source code with proxy/repeater
    %programfiles%\ultravnc\vncviewer.exe -autoreconnect -connect ID:1234 -proxy repeaterhost:5901 -quickoption 3 -dsmplugin SecureVNCPlugin.dsm -listen

    * reconnect is not work from commandline, need use filename.vnc

    * wallpaper center
    is stretched on viewer disconnect only as system service (like bug of aero before 1.0.8.x)

    * switch user on controlled computer (ultravnc server),
    vncviewer is disconnected, reconnect is possible with vncviewer .... Options... 1 reconnect... OK
