Well that one approach, I'd rather debug the problem.

  I was "hoping" for exactly what I have had working for the last two 
years. Calling gnuplot NON-INTERACTIVELY to plot some real-time data.

Your attempts at being a sarcastic smart-arse would look less stupid if 
you did not make sweeping assumptions. No where did I suggest I was 
running gnuplot interactively.

Ethan's suggestion has enabled me to establish that this problem is more 
general than the call to gnuplot. So I won't discuss this further on 
this list.

Now fixed.

Thanks Ethan.
