Dear All,

Now in the Microsoft excel 2007 we have track changes but every time I use
it nothing happens as of its not working at all, while in other versions of
excel it works normally with no problem.

I don't know why specially this version 2007 that it doesn't work for me,
may be I am not using it the right why???

can anyone help me to tell me how to use it.

Best regards
Mohamed
