Hi,

As for the latest compiled WinGRASS7, which at the moment (from osgeo4w) is r55677-547, then this gives the error right at the startup of grass7 (i.e. after g.gui command):
GRASS 7.0.svn> Traceback (most recent call last):
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\gui\wxpython\wxgui.py", line 34, in <module>
    from lmgr.frame import GMFrame
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\gui\wxpython\lmgr\frame.py", line 69, in <module>
    from lmgr.pyshell          import PyShellWindow
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\gui\wxpython\lmgr\pyshell.py", line 27, in <module>
    import grass.pygrass as pygrass
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\python\grass\pygrass\__init__.py", line 17, in <module>
    import modules
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\python\grass\pygrass\modules\__init__.py", line 11, in <module>
    import grid
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\python\grass\pygrass\modules\grid\__init__.py", line 9, in <module>
    import grid
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\python\grass\pygrass\modules\grid\grid.py", line 20, in <module>
    _GREG = Module('g.region')
File "C:\OSGeo4W\apps\grass\grass-7.0.svn\etc\python\grass\pygrass\modules\interface\module.py", line 87, in __init__
    raise GrassError(str_err % self.name)
grass.pygrass.errors.GrassError: "Module 'g.region' not found, please check that the module exist"

Therefore I've been using an older build (r55595-540) with which I have this curious vector layer deletion issue (which I'm sure I didn't have a few weeks ago at least). It doesn't matter whether I try to do it in a script or not, g.remove does not remove vector layers completely. It seems to get stuck with hist file. There is a chance though that the issue isn't apparent in a newer build.
One probable solution would be moving on to Unix though.

The GRASS 7 I'm running currently however is a week-old r55595-540 as the
later ones have been giving the error regarding pygrass and g.region at
startup. Could this be the key to my issue?

Can you provide the code that you are using?

As I said in grass-dev[0], at the moment the shortcuts are not working properly.
