"Do you want to save changes" not working...

[Ambrosia]

I copied an excel chart into powerpoint as "Excel Chart (entire workbook)" so
that it would not have any links to the orginal worksheet. When I then go in
to edit the data the changes are made to the chart however if I close the
powerpoint presentation it does not ask me if I want to save my changes, and
when I reopen the presentation the chart goes back to the orginal data. If I
consciously save the presentation before closing it, the changes made,
however I'm afraid I might close it without remembering to save it since I'm
not prompted. Is this a problem with 2007? or am I doing something wrong?
Anything I can turn on to get the prompt to work?

What you're experiencing is highly unusual. I know this will sound odd, but
have you rebooted recently?
