• .Incident Diagnosis
  Although a value is defined for "Undo Stack Size",
  it is possible to Undo more times than that value.
  .
  A great number of consecutive Undo actions can be
  performed while the option "Stack size" has been
  used to limit it.
  This is probably because the user started a global
  action. In that case, this limit does not apply so
  that it is possible to cancel the whole action.
  .
  .Correct Application
  R16 documentation says :
  Stack size Lets you indicate the number of
  commands (from 0 to 99) which can be undone for
  each document.
  Whatever the value, it is always possible to undo
  internal transitions (also called "local actions")
  inside the current command ("global action").
  .
  Note that a global action can be :
  - a command;
  - an edition in context (double-click).
  In "Undo with history" dialog box, the beginning of
  a global action can be recognized as it begins
  by "Start " (but the default "Select" command
  which does not stack a "Start Selection..." step).
  .
  Always open "Undo with history" dialog box when
  you do not understand Undo/Redo behaviors, it
  helps looking at which steps are stacked.
