Since google couldn't find any solution for this, I just thought to share it here - and to thank you for your post, of course ;-) The connection.close() trick solved a problem I had when using the sqlite3 backend: My Django app runs as a win32 service and locked the sqlite database whenever an IntegrityError occurred, so that other non-service apps could no longer access the database.

How did you manage that kpasswd is used instead of passwd? Thanks a lot, Stephan Hi Chris,

FYI, your link to "Larry Stevens’ excellent jQuery plugin" now takes you to a "Social Survey" page that you cannot get past. I suspect that the page has been hacked. I would suggest this link instead: http://dropshadow.webvex.jux.com/ Nicely done.

Are you still interested in a good rps ai, bacause I've been thinking about this recently.
