Thanx Trevor,

Hi,
Not sure if this is the problem, but if your script is bailing out with an error before plend() is called then next time you run the script it will try to open plplot when its already open. There may be a better fix, but if you just call plend() before rerunning your script it might solve your problem
Regards,
Trevor.
