I could put in the help text "zoom to current global region setting" Would
that help or confuse?

I don't know if "global" is clear in this context, as it might be interpreted as the whole (default) region. But I don't have any better idea (except for using g.region in the text...).

Subject: Gis.m display fails to update to new region changes with
g.region

Platform: GNU/Linux/x86
grass obtained from: Trento Italy site
grass binary for platform: Downloaded precompiled Binaries
GRASS Version: Grass 6.1 cvs binary snapshot 2006-03-04

Gis.m doesn't update the display to new region extents on subsequesnt
redraws.

Ex: If I zoom into a small subset of my currently displayed raster,
and type g.region -p:

projection: 1 (UTM)
zone: 20
datum: ** unknown (default: WGS84) **
ellipsoid: wgs84
north: 5174033.36548
south: 5172592.47662
west: 634545.579594
east: 635650.346057
nsres: 5.18305345
ewres: 4.8243077
rows: 278
cols: 229

Now set region to full extent of my raster:

g.region rast=myraster

projection: 1 (UTM)
zone: 20
datum: ** unknown (default: WGS84) **
ellipsoid: wgs84
north: 5175138.55197738
south: 5166979.86985776
west: 628088.36633083
east: 652649.9283519
nsres: 5.51262305
ewres: 5.02589769
rows: 1480
cols: 4887

But redrawing shows the same extent as the first instance when I was
zoomed in, despite g.region showing a larger extent.

After g.region press "Zoom to current region" in Map Display window,
then redraw. Is it OK then?

Maybe this should be changed to something like "zoom to g.region
setting" to make it clear that this means the current region set
globally in GRASS and not the current region of the monitor.
