AJ, that's twice now... You need
much better NDA's with your beta testers. Too much damage was done with the leaked OS3 beta for you to allow them to leak to the users (who seem to not realize that 'beta' MEANS it ain't ready for the public, yet!
) as much as this.
Maybe you could 'watermark' each beta, and find out WHO is doing this? He's not helping, that's for sure...
