Track/Accept Changes

[WhOkNoWs]

Just did the conversion to Office 2007 a couple of months ago.
I have a shared workbook used by several users and I go in daily and track
all changes, make any necessary corrections and accept the changes, then save.
The Problem, when I go in the later to highlight the changes "not yet
reviewed" by "Everyone", it highlights everything from the past. I only want
to see highlighted changes for the cells "Not yet reviewed".

Please help!!! Am I missing a setting or something??

Thanks!
