giz--the last thing you want to fiddle with is your OS! I recall (months ago) some people complaining that the "10.2" turned out to be a porn flick or the pre-release version. Looks like some people need to inspect their shared folders. You could try chatting with those folks and finding out if the .dmg's really do work. Frankly though, I wouldn't risk it.

There might be a Disk Copy 10.2.3 in my idisk that you could look at, but I doubt that will help. Glad to hear that LW is worlking well for you.
À votre santé.
