+Hi,
+
+thank you for the latest Postgres95 distribution! 
+
+>does the createuser bug still persist, or have
+>we finally worked that one out?
+
+As has been indication by Bruce Momjian, the createuser problem was
+caused by a bug in flex 2.5.3 (which has been confirmed by Vern
+Paxson, the flex maintainer - many thanks to them); the bug will be
+fixed in flex 2.5.4. Vern Paxson has been so kind as to supply me with
+a patch that will be part of the 2.5.4 release; I'm including it below
+in case someone has installed flex 2.5.3 and doesn't want to go
+back to 2.5.2...
+
+Regards,
+
+Ernst
