Hello
This is a record from my experience about ginput.
If you have installed the octave-forge plot package, the function ginput does not work because the
plot package also has ginput.m and made conflict with ginput octave itself.
Please rename .....\Octave\3.2.4_gcc-4.4.0\share\octave\packages\plot-1.0.7\ginput.m like
ginput.xx.m.
For old PC, response of ginput might be slow. (might take several seconds to respond).
This is due to the pipe handling on windows being not optimized.
To overcome the slowness, the same technique to improve plot speed proposed by Olli Saarela can be
used.
Please refer

sleep(0.05);
