In the server settings there is an option, under Administration, on how to behave when a second connection is recieved. (Right click on the taskbar icon) In Presence VNC, when you choose then connection, click QualityIf you are on a LAN select the LAN option If you are running over the internet select the ISDN option I run dual screens both @ 2560 x 1600 full colour (LAN option) with Presence VNC over a LAN with no speed issues. So I assume it's your connection speeds, use the lowest Quality option. ___________________________________________ Addison, dfmirage is still there on the download page for TightVNC v1.3.1 http://www.tightvnc.com/download-old.php The current version of TightVNC doesn't utilize dfmirage yet, as dfmirage has only just been adapted for Window 7
