 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:

 WELCOME TO GRASS              Version 6.3.0RC6         2008

    1) Have at your side all available GRASS tutorials

    2) When working on your location, the following materials
       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?
