Yes, I was thinking of trying that route to see if the same thing happens there. Haven't yet found time to do that but i will and then report.

BTW: I've run many other queries in a similar manner against other comparable data in this database and do not remember having had this problem before but I am well aware that ALL software is buggy and sometimes strange results come from previously routine queries so I thought it worth posting the question to see if any one else has had similar experiences with this type of data in this type of query.

Thnx for your feedback. /psb
