I just realized that this would happen last night. This is due to each map
display having its own, independent region settings. I have a fix planned (a
button to display map in current region).
Until I get a chance to create this, there is a simple work around.
In g.region, save the region to a name. Then use the 'zoom to named region'
button.
You can also save it to "mon_#" where # is the number of the map display
(top of window), and press the display button.
