Try doing a repair, or better still, an uninstall and reinstall. And you'd
better get familiar with that procedure.

I have been playing with Excel 2007 at home and have noticed roughly two
out
of every three time that when I close Excel, it brings up an error message
that Microsoft encountered a problem on close and needs to close.

(I just tried it again, and this time it brought up Office Diagnostics).

Is anyone else having this problem? It is not every time I close Excel,
but
it is becoming more frequent.
