Hello-

Has anyone seen this behavior?

Working in a simple spreadsheet in Excel 2007.  OS is Vista Ultimate.
(Dual core AMD/3 GB RAM)

Three times today, and a few times previously Excel 2007 locks up and
then causes a reboot of my PC.  Upon the completion of the reboot, a
message simply states that Windows has recovered from a serious
error.  Event logs seem inconclusive.  Issue only occurs when using
Excel 2007 and has been fairly easy to replicate.

Unfortunately this is not the only bug that I have experienced in
Office 2007.  I have experienced many slow downs (but no reboots) with
Word and even more serious issues with PowerPoint.  I experienced none
of these types of issues with previous versions of Office.  Office
Diagnostics finds nothing wrong....

Thanks in advance for any comments.
