Hi Jeff,

  I tried the volume "update show" option in combination with volume 
planes and did not find an problem.  Can you give me step by step 
instructions to produce the problem?  Also I don't know what you mean by 
"does not work".  Does it always update automatically, or never update 
automatically?  What Chimera version?

  With the volume planes tool, the full map is still opened -- it is 
just display a subregion that is 1 plane high.  Use Features / Region 
Bounds to see and change the subregion.  Or use Features / Subregion 
Selection and press the Full button to get back to the full map.  Also 
the volume planes dialog always acts on the volume displayed in the 
volume dialog.  Perhaps it should have its own menu to choose the volume 
you want to show planes for.
