I used the new Windows installer package to install GRASS 6.3.0RC6 on my
PC. I installed GRASS to c:\GRASS and tried running the startup script
found in c:\GRASS\msys\home\users\john using the msys shell. Here is a
transcript:

       are extremely useful:
       - A topo map of your area
       - Current catalog of available computer maps

    3) Check the GRASS webpages for feedback mailinglists and more:

I have Python 2.5, wxPython widgets, numPy, and the python extensions
suggested on the installer download page. These are installed in
c:\Python25. My computer uses Windows Vista. What do I need to do to fix
this?

Comment:

I apologize for reporting this trivial error. I found that the root of
this problem was that my [[BR]]
GIS data directory had been set to 'c:\grass\GIS Database'. This is the
default value[[BR]]
when winGRASS is installed using the experimental installer program. The
space in the[[BR]]
directory name was causing problems inside the Python code. When I
changed the GISDBASE[[BR]]
variable to a path without spaces, the wxPython GUI launched correctly.

Reopening as all failures due to spaces in path's need to be fixed sooner
or later. Changed ticket summary to match problem.

Under Windows XP wxGUI seems to work even with whitespaces in path.

{{{
g.gisenv.exe
GISDBASE='C:\grass data';
LOCATION_NAME='spearfish60';
MAPSET='PERMANENT';
GRASS_GUI='wxpython';
}}}

I started GUI without visible problems.

I confirm, as Martin, that on XP spaces in GISDBASE don't create errors;
this is apparently another Vista problem!

Could you try with tcl-tk GUI, please?

I tried using the path 'c:\grass\GIS Database' in Tcl-Tk and it worked
fine. I guess that this is a wxPython problem, then?

John,

I think we should say that is a "wxPython/Vista problem".

Comment (by hamish):

I think it is a very big call to say that "on XP spaces in GISDBASE don't
create errors". I will guarantee there is somewhere in the code which
doesn't quote a path name and so will have problems with a space in one,
regardless of OS.

Before labeling things as "on Vista", I'd like to know if someone else can
confirm that? And if so, is this really a wx for Win bug not a GRASS bug?

{{{
..\..\src\msw\listbox.cpp(390) in wxListBox::DoSetSelection(): invalid
index in wxListBox::SetSelection
}}}

or did we pass that a truncated entry?

Also, I don't really see the point in leaving a bug report open for a
vague things like "may cause problems". We know that, but it's something
that is very hard to systematically audit, so we just have to wait for
specific bug reports to roll in..

2c,
Hamish
