what are the new packages that you are referring to?
i'm using the open public beta 4 and it returns the following when trying to overwrite the initial Simple Machines team message with my own:
(this is from "track user" info):
8: Undefined index: %s
File: /PATH-TO-SM/Sources/Post.php
Line: 641
?action=post2;start=0;msg=1;sesc=[...];board=1

deleting the guest post and posting my own works fine.
also if i change only the user name and click Save, it works! And then change the message body and click Save, it works again. But if i change all the details at once, it results in the message above.
using win2k with the latest IE with the SQL server running on a linux box.
