Problem: 1383813
Title: (Undo/Redo) Undo switches between contexts.
Received: Aug 30 1996 7:33AM
When undoing and/or redoing multiple commands the context switches as the commands
are undone/redone as though we had a single context. This makes it impossible to
undo/redo something in one context without having to undo/redo everything in every
other context stacked above the desired context.
Undoing/redoing should proceed only through a single context's stack.
Fix:
Fixed.
