The scenario is clear. You know what I personally would do it occured to my code? I would work to create proper orphan mode for opened instances. Then, new device would get assigned number 0, even if someone had device 0 still open. The internal structures for the old "device 0" would have been kept alive by a (counted) reference from the top side as zombies, to disappear when eventually closed. It may be too much work for you, your call. It's easier to suggest than to implement properly (without leaking or other bugs). -- Pete ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
