Comment:

 This issue seems to be caused by "clever" $HOME tricks by MSYS (?). $HOME
 is set to /home/%USERNAME% and it points to "C:\Program Files\GRASS
 6.4.SVN\msys\%USER%". The catch - there is no such folder as %USER% as
 %USER% migh not have permission to mkdir there. MSYS deals with it just
 fine - it "fools" every call that folder exists. Still it doesn't help
 Python or TCL, as they bypass MSYS and thus don't see MSYS dirty $HOME
 tricks.

 Working solution for Vista users is to add following line to beginning of
 the msys.bat file (seems to work OK also if %USERPROFILE% contains
 spaces):
 {{{
 set HOME=%USERPROFILE%
 }}}


 Here's some output for a new user "tests2" under Vista running 04.06.
 WinGRASS 6.4. (without %USERPROFILE% workaround and with some echo's and
 print's):

 Here's some output of gis.m after changing startup to use -tcltk instead
 of -wxpython (mentioned directory really doesn't exist):
