Yes, I did. Here is my cygwin_grass.bat file:

    @echo off

    chdir C:\cygwin\bin


    bash --login -i -c startx

If I run just the last line at the command prompt:

    bash --login -i -c startx > c:\cygwin\all_out.txt 2>&1

I get the following all_out.txt:

And X does start (it is an X terminal and if I type grass62 and hit 
return, GRASS starts just fine). But if I manually run at promt:

    bash --login -i -c startx

the next thing I see is the GRASS startup message

    Cleaning up temporary files.....
    Starting GRASS ...

And no X runs. GRASS starts in text mode but then it tries to load a GUI 
and off course this fails.

Hope I provided some useful info. Thanks in advance,


P.S. I also added the following at the and of .bashrc

# Start GRASS
if [ -n "$DISPLAY" ] && [ -n "$GRASS_AUTOSTART" ] ; then
   exec grass62
