So on 9 May I could reproduce what Dave showed exactly.  I can today (26 May)
no longer reproduce the bug.  Possibly this is my use of 1.5.8 - 
pcp-gui-1.5.8-2.el6.x86_64
as an rpm.  I'll downgrade to sgi's version.

You can choose a ready guide in some celestial voice.
If you choose not to decide, you still have made a choice.
You can choose from phantom fears and kindness that can kill;
I will choose a path that's clear
I will choose freewill. - Lee/Lifeson/Peart
