Perhaps you should only do this if the slider was not moved manually in 
the meantime, and the cursor position is at the end (or something like 
that). Otherwise, users won't be able to scroll comfortably and take a 
little bit of time to read the log messages. It is *very* annoying if 
you try to read a log, and it keeps scrolling away to the end because a 
new message has been added...
