I think the 'problem' the original poster was talking about was related to what happens when mirc or (more likely) windows crashes and the automatic merge does not occur (and/or corruption?)
IMO, the underlying crash issue should be fixed, not changes made to software to accomodate it. (if indeed that is the case)
I guess during a crash of some sort the merging does not occur, and if you dont remember to do it manually things could become a mess, or entire time periods missed, etc.
Maybe a few logging options such as 'automerge on startup' or a command/timed automerge feature could be useful for both crashers and mircstats users.
