| gnuplot works perfectly, but when the last command displays the "a" vector,

the browsing

| I use the following binaries:
| 
| octave-2.0.13-i386-pc-cygwin32
| less-gnu-win32
| pipe-gnuplot
| cdk

So you are using the cygwin b19 library?  I wonder if this problem is
solved by the b20 library.  Can anyone else who is using Octave on a
Windows platform reproduce the bug, or confirm that it is not present
with some other version of Windows (95, NT) or with a newer version of
the cygwin libraries?

I no longer have easy access to a system running any version of
Windows, so I can't debug this problem.

Thanks,
