Personally, I really like the way autoscroll works now.  But Ulf makes a
good suggestion in that it may also be nice to stop the autoscroll if
you click on a packet of interest.   Then resume the same way as now.

This was added by one of the guys here at CACE, and checked in in
r22277. It's
intended to let you go back and look at any interesting traffic that
might be
flying past during a live capture by simply grabbing the scroll bar.
Modern
terminal programs have this behavior, e.g. when PuTTY's "Reset
scrollback on
display activity" option is disabled.

How is the scrollbar position "invisible"? If you're at the bottom, then
autoscroll is enabled. If you're not, then autoscroll is disabled. At
any rate,
the toolbar icon should reflect the autoscroll state. We'll work on a
fix.

automatically?

If we want to be consistent with PuTTY, Terminal.app, gnome-terminal,
and other
applications then the answer is "yes."
