    Hi Mary,<br>
    Thank you for your continued work on this (I was on vacation last
    week). Unfortunately, I probably can't test the VM solution. After
    consulting with my IT security person I learned that NASA is
    extremely anal about VMs and it would not be wise for me to attempt
    running that software on my work computer. My Windows Vista computer
    at home is an older computer and may not have enough memory to run a
    VM. I will definitely keep this solution (using a VM) in mind as it
    seems like NCL may not work well with current and future versions of
    Cygwin.<br>
    thanks,<br>
    Kevin<br>

                                    The "gsn_open_wks" function also

                                    working fine under an older version

                                    my Cygwin version and always get the

                                    but that<br>

                                    NCL has very limited functionality<br>
