Autocutsel synchronizes the two copy/paste buffers mainly used by X applications. It unifies "clipboards" between VNC servers and Windows. The 'cutsel' binary performs the synchronization whenever it is run. The 'autocutsel' binary performs the synchronization continuously. I suggest running it from ~/.vnc/xstartup by adding a line like this at the top: exec autocutsel & WWW: http://www.nongnu.org/autocutsel/
