I am running LISTSERV 1.7c. I've encountered a problem when PUTting a header back. I can only do it once per startup of LISTSERV. I got a list header. I changed it and sent it back successfully with LSVPUT. Then I changed my mind, changed the header again, and tried to PUT it with LSVPUT. LISTSERV sent me a note explaining that the header did not contain the proper statements (starting with an * in col. 1). I shut LISTSERV down, started it again, and successfully performed an LSVPUT with the same header, no changes since the last attempt (the one that failed). It doesn't have to be the same header. Only the first PUT succeeds. We only have 3 lists here. But I've experimented with a few variations of the above and the consistent fact is that only the first PUT works. Help. Anyone?
