Details:

using qt plot 
when copying a graph from surf plot, and then pasting it when the data values
are high or low, there seems to be a long delay, maybe due to the number of
points but whether it is due to impatience on my part or the system taking a
very long time.
This might be the system calculating and trying to get the data for the image,
e.g. x,y,z is probably 10,000 + points in total. 

When I print screen or paste the data is not pasted and the system takes a
long time to respond so I have to close Octave and restart again.

Make a surf plot with 100x10x100 points, go to edit, then go to copy and try
to paste it quickly in an email application.
I have many tabs open at present in google chrome and a lot of memory is being
used too so this would also be an interesting thing to try out in repeating
the problem.

Is this the same as the one below?
