Even so I doubt it will be very reliable :( I did create a diff that might help but noone tested it (and I don't have an MGE UPS handy at the moment to test it myself) Note that while this will still cause data to be dropped it should a) log the fact, and b) do it in a way that doesn't cause the UPS driver to get out of sync. ugen should really be fixed to not use clist buffers but that can wait for another day :) -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
