Thx Jeff,
i mentioned my SC-use a couple of posts ago, but its easy overlooked 
. I know most of the RS experts use the command line for everything, but we only have a very simple warm-standby environment which runs very stable, so i don't have to do a lot in the RS (when you have to perform the commands only a few times a year, its hard to remember them). This is why SC is very handy for us...
i think i understand what you're saying, but how come i saw only the updated columns in our 'old' environment? (not that important, i'll remember that this queue does not represents what is actually sent)
As for the where-clause: still only the PK in the clause. (yes, i checked the dsi_buf_dump)
Its no drama if this is the new behaviour, but like i told Mark, we liked this because this was error-detecting when a record was not in sync any more...
