The built-in PHP session handler handles this by LOCKING the session for writing until it is closed and done for each request. The simplistic example for user-defined handling sessions in the manual does not, in fact, address this directly. The User Contributed Notes, last I checked, did have some rather sarky comments about this issue, and some suggestions for how to fix it. If you are using a database, for example, locking via some mechanism in the DB is probably a viable solution. Wrapping it all in a Transaction is probably overkill, for example, but would work. Of course, the simplest solution remains: Don't use frames. -- Like Music? http://l-i-e.com/artists.htm
