Hello 
  Don,
   
  The 
  philosophy of all Subversive drop-down menus is to show all the actions, that 
  can be available in some context, so that the user can always see what he can 
  do in some cases from the view;).
   
  So, 
  talking particularly about History View, I must mention, that in your case the 
  describer actions can be enabled, when the SVN 1.5 connector (Java HL 1.5.0 or 
  SVN Kit 1.2.0) is selected in such conditions:
   
  1. Single 
  selection case.
      a) Compare with Each Other - disabled, cause where is 
  Each and where is Other?:)
      b) Compare Current with <Rev Number> - compares the 
  current state of your project in the working copy with the selected 
  revision of your project.
      c) Compare with Previous - compares your 
  project in the selected revision state and in previous to selected 
  one.
   
  2. Double 
  selection case.
      a) Compare with Each Other - compares your project state 
  in the selected revisions.
      b) Compares, enabled for single selection, are 
  disabled:).
   
  So that's 
  the brief description of this menu part of the History 
  View.
   
  Best regards, Alexei Goncharov.

  All,
I'm using the Eclipse Subversive plugin, looking at the 
  History view for a project.  When I select two revisions, I can 
  right-click and see the context menu, which contains a few Compare options, 
  all grayed out.  Are these placeholders for future features?  I'm 
  particularly interested in the Compare with Each Other option.  Or is 
  should it be working now?  Just trying to find out the 
  status.
Thanks,
Don
