From 1cbef0b9084bce0816c7ef471b3b58d1dbf9de7c Mon Sep 17 00:00:00 2001

Subject: Patch from Michael Osias IBM (jimbo2120) In his own words: If a prim
 becomes a listener or remote channel and the script is deleted, it cannot
 become a listener or channel again with a new script. This patch fixes that.
