the problem with this case is that there is no tool to modify the default window
(except for r.in.gdal -e and you need to have the right file to do it)
so you are stuck with 1x1x1 and it propagates to each new mapset when you create it.
For old users it is OK because we all know that we need to set the region
before doing anything and if we find the 1x1x1 DEFAULT_WIND annoying
we can edit it directly or copy a properly set WIND to DEFAULT_WIND.
But for new users it can get pretty confusing.Probably adding an option to g.region to modify the DEFAULT_WIND when
PERMANENT is your current mapset would solve it along with a message asking
the user to do that after setting the location from EPSG, or PROJ parameters.
I agree about g.region, and about the startup GUI (currently gis_set.tcl) I feel it should allow the user to set the initial region there and then. The text-based location creation (etc/set_data) does this and I think the graphical startup should too - as you said everything assumes that the default region is an attribute of the location that has been explicitly set when it was created.
But as the Tcl/Tk GUI interfaces to grass using commands, I think adding an option to g.region to set the default region is a pre-requisite for this.

It would be very convenient if the option included possibility to copy the current
WIND to DEFAULT_WIND. This would be useful also for situations when the user
wants to change the DEFAULT_WIND for whatever reason (for example if he
works with many different regions and wants to have one that covers all of them
for convenience).Thanks a lot for looking into this - we are finding all kinds surprising problems
when working on the book that probably new users have to go through and that
normally do not bother us,Helena
