inserts on an authenticated DB like mongoHQ.com with safemode=false do not work. works with safemode=true. I've tried with latest release and also with latest source from https://github.com/mongodb/mongo-csharp-driver.git with same results. Only information I could find on this on google is http://groups.google.com/group/mongodb-csharp/browse_thread/thread/401006010e7c6fe8 where some fix seems to have been applied. Was that applied to some other driver?
