The old dialog with the old behavior is still in the program, and you can
put it on the Tools menu.
Open the Tools > Customize dialog. Select "All Commands" in the Categories
list. Scroll the commands list down to find ToolsReviewRevisions. Drag that
command out of the dialog, hold it over the Tools menu until the menu drops
down, and drop the command in your preferred spot in the menu. It will
appear as "Accept or Reject Changes..." Close the dialog. When you close
Word, if prompted to save changes to Normal.dot, say yes.
