[ncl-talk] NCL 6.2.0 hanging on startup

[Mary Haley]

Hi John

I'm with Rick in that I haven't seen this before.

On Windows systems there's an issue if you try to run "ncl" under a 64-bit
version of Cygwin. It must be run on a 32-bit version. But, what usually
happens here is that you get the UNIX prompt back with absolutely no output
echoed or any warning whatsoever.

On some Linux systems, we've seen issues where one Linux binary may not
necessarily work optimally on a different flavor of Linux.  If this is a
Linux system, then you might try a different Linux binary for NCL. If
you're going to do this, then I also recommend that you upgrade to NCL
V6.3.0.
