I guess I wasn't accurate in my describing the situation. The customers in
this are employees in the office and so speed would not be an issue.
You're right that I could display part of the map as opposed to the entire
map, but displaying the entire map would have other advantages.
It's not a detailed map to begin with, doesn't have street names, and
looking at just a section may not be enough to know where this section fits.
I know I can highlight a section if I make two copies of the map - the
original map with white background and smaller pieces of the map in yellow
background.
At the same time, having two copies of the map doesn't appeal to me.
Thanks for all so far,
