Hi John, You need to also add a port for view events. Using 'dispatch makes it easier to react to different ports. See note below about the attached script. ? dispatch USAGE: DISPATCH port-block DESCRIPTION: Wait for a block of ports. As events happen, dispatch port handler blocks. DISPATCH is a function value. ARGUMENTS: port-block -- Block of port handler pairs (port can be timeout too). (Type: block) ;--------------------------------- The attached View script communicates a message to each member in its client list. To use... Run 3 instances of the script and set the port numbers to 8001, 8002, 8003 Now anything you type in one will show in the other two. Hope this script helps someone. Cheers, Allen K
