Hi, this relates to earlier messages, including from me, about problems
with the region settings. It seemed to be solved, but I am again
experiencing similar problems as reported below.
Like Michael, I tried different functions, like r.patch and r.proj, and
they all give trouble when used with the GUI version of the module. But,
as Michael reported, the same modules work fine when used on the command
line.
This is indeed a serious problem, but hopefully the pointer that this is
related to the GUI version of these modules might help to identify the
problem.

This is really odd.
I've been using GRASS 7 (compiled yesterday) trying to patch together
a 90m DEM with ocean data downscaled from an ETOP2 DEM.
I repeatedly was getting files with a resulting resolution of NS Res:
0:00:50.139276 and EW Res: 0:00:53.20197 even though I repeatedly set
the resolution to 3 arc sec using g.region.
I've discovered that this is what happens if I interpolate points,
resample rasters, patch rasters, or run r.shaded.relief (a script)
using GUI versions of GRASS modules.
But if I do EXACTLY the same thing from the terminal command
line--even with copying the commands from the GUI--I get the proper
90m (3 arc sec) resolution.
Anyone have any idea what is happening here? This is potentially
serious for analysis.
Michael
