It's not generating the hash that was bothering me at the time, it was more that the hash is not unique in theory, and that you would still need to have conflict checking code in case it wasn't. But I guess the likelihood of that happening is immensely close to zero, and if you have a timestamp in there, it would be even closer to zero happening twice in a row (i.e. the "Why didn't this work? I must have done something wrong, let me try again"). So I suppose I should learn to live with imperfection ;-) cheers, Remko
