Hey Robin:

I just tried this, and I'm not getting that behavior.  In over a decade 
of using Scilab, I haven't seen that behavior.  So I'm not good for much 
help.

Two things that you can try, however, are:

1: If you haven't yet, try it again, in case the Evil Computer Gods have 
been messing with your head.  Maybe close Scilab and open it again.

2: Tell us what Scilab version you're using, as well as what OS.  For 
your Scilab version, type getversion (e.g. mine is Scilab-5.5.1).  This 
won't help me help you, but it may help someone smarter than me help 
you.
