Entry for 1st January, 2009 - Tracked Changes

Does anybody out there actually know how to worked Tracked Changes on a Microsoft Word Document properly? I toy with it every now and then at work when I’m revising contracts, but every time I do, my document quickly becomes full of mad boxes and lines and stuff. Little messages like this appear –
“AB deleted a whole lot of important stuff by accident that is now gone forever.”
And
“Formatted by a juvenile monkey on an acid trip.”
