Thanks for this information, it lead me to discover the bug in my code. The
problem was that a "set term x11" command was issued to gnuplot when the the
external plotter pipe was first initialized. This lead to gnuplot_x11 being
launched before mouse settings could be altered, and so it was started
with the "-noevents" option, which seems to be the default for piped IO.

Since there seems to some interest in this patch, I'm currently trying to
compile a version of Octave with gnuplot commands moved completely from
the parser and lexer to an external .oct-file. I'll post the patch later
today or tomorrow if I succeed.
