Hi Theslaz,

If I
press the "Save" icon in the tool bar, Excel will show that it is saving
the worksheet in the lower tool bar. It will say "saving Master Invoice"
and then ready. If I close and re-open the worksheet; I will find that
nothing was saved.

Are you SURE you are opening the same file after this save?

What happens if you start Excel in safe mode (hold the control key when you
open Excel)?

What Excel version?
