You are right. Early VNS in course up and look-ahead would crash on
zoom. Fortunately long behind us now.

Subject: : North Up or Course Up?
We now use VNS in the Course Up mode and the look ahead mode. We have
all
of our charts on the hard drive and run Windows 98 on my Dell 8000
laptop.
It took a while to get used to course up because my brain remembers what
the
paper charts look like in north up. AND the earlier versions of VNS
were
very volitile in the course up mode. You could crash the program by
zooming
in or out or by changing charts so we used to reserve course up for only
deep fog so we could coordinate with our radar.
We still have the same computer but the new VNS runs great in course up
and
we use it all the time even on sunny days. It is most useful when
navigating between rocks and islands. (Reid Passage in Northern BC
comes to
mind.) We usually have a big overview paper chart on the chart table
and
use VNS in course up.
Bob says he votes for course up too.
