Re: initialization bus error

Hi Jim,

Nothing comes off the top of my head on this one. The HLU library
gets initialized during a call to Ngl.open_wks. You are allowed to
call this function multiple times, so I don't think multiple
initializations are a problem.

Can you give me some information about the "plotNgl" routine? This is
not one of our routines. I'm guessing this routine must be calling
Ngl.open_wks to create a workstation to draw the graphics on. Perhaps
there's something about this call that needs to be fixed.
