It occurs to me that the problem is likely related to the figure's  
current axes.

Is there a way to restrict a specific axes from qualifying as the  
current axes? (I suspect the hidden axes used by gnuplot_drawnow to  
hold the figures prior position property is the probem ... although I  
have no idea how it becomes visible).

If not, then a different solution for storing the prior figure  
position will be needed.

I'll propose an approach either later this evening or tomorrow.  
However, I'd prefer to find out how a hidden axes becomes visible  
before committing a solution that hides that feature/bug.
