Hi Igor...
You can not run the commands from the windows shell...you need to run them
from a Cygwin sh or bash shell...otherwise the "detach after authentication"
will not work.
If you have the commands as typed in v.bat then execute the file with the
following command typed in a windows command shell
C:\Cygwin\bin\sh.exe "C:\...path to file...\v.bat"
You can also use the above line in the target field of a shortcut to get
double clicking to work for you.
Hope this helps,
...Karl
