time machine only shows current version
I updated last week to 10.8.3 from 10.6.8.
Went to Time Machine to retrieve an earlier version of a Word file I'm working on, and every file that I can access in Time Machine thorughout the day or from yesterday is identical to the current version. The bars on the right are alternativing gray and purple, too.
I was hoping to retrieve an earlier version of the same file. Is this possible?
