RE: Simple .cmd file works under Cygwin but not Window's cmd interpreter.

Andrey -

Thank you for the response.   I had already tried most of your suggestions in one form or another.    So below is my
latest try (reduced to the essentials) to find what works and what doesn?t.  The essential idea was to take the PATH out
of consideration by reducing it to a minimum in both the CMD and Cygwin environments.   This did not change the result
at all.  This is expected, because Crystal Reports does not itself depend on anything in the PATH.  The user defined
functions are dynamically loaded and installed when run under Cygwin but not when run in a Windows command window.

There are differences in the environments (attached) but I don?t see anything Cygwin has added or changed that would
make a difference.  After all, Crystal Reports knows nothing about Cygwin specific environment variables so anything
added by Cygwin should not affect the behavior.   There are a few things that are different (oddly) , but manually
setting these in either environments is a bit tedious.

Now there are some details about the way user defined functions are installed that are peculiar.  First of all,  the
CLASSPATH settings are obviously read from the registry by Crystal Reports, not from the environment.   This is one of
the nasty manual configuration settings I mentioned below.    It also reads the path to a JVM .dll from a registry
setting and this also has to be set  to get user defined functions working.   When running  the script below in a
Windows CMD window,  Crystal reports loads and runs, but it fails to load the user defined functions.  That works from a
bash prompt.   From experimentation, I know setting this registry value is necessary as running in the Cygwin
environment fails if this is not set.  It is possible, that there is something strange about .dll loading which causes
it to work in Cygwin but not on a CMD Window, but that seems unlikely.

@Echo off

set CR_HOME_DIR=C:\Program Files (x86)\Business Objects\Crystal Reports 11.5

:: Display CLASSPATH

:: Set and display JAVA_HOME
set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.6.0_45
echo %JAVA_HOME%

::  Set minimal path and add 32-bit JDK to PATH and display
set PATH=.;%JAVA_HOME%\bin
echo PATH
echo %PATH%

:: Display environment.  
java.exe -version

I am still very puzzled,
