The active users script used a text object to list the user
names. This was a bad idea as it turns out to cause problems: If
someone moves a node, the text showing the user list will stay on its
position on the map which can cause confusion. Restarts do not work
with the usual mechanism, as the text object has no IP address
attribute (which was your problem).
I changed the active users script to write the user list into the
`active users' attribute of the node object. This solves the problems,
although it may not look as nice if you have lots of users on one
machine. Below is the patch for ip_monitor.tcl.
