Yes, I checked the user's event log and nothing gets logged.

Yes, I have run hardware diagnostics on the memory, the hard drive is a
server that appears to be running fine.  This is a relatively new computer,
I upgraded her to try and fix this problem last year on a different
computer.

No, the user does not have a personal.xls file with macros in it, she
doesn't know how to create macros that I know of.  Not sure what a
personal.xls is though.

I have suspected a corrupted Excel workbook or Power Point file but the user
insists it's not repeatable and she can't see a pattern.  She does admit
that her workbooks are often contain dozens of worksheets and that her Power
Point presentations might have up to 80 pages.  We do have a business
application, written in Java, that is a huge resource hog and the user did
say this morning that she sometimes gets messages about the page file being
full.  I'm now wondering if more memory is in order.

I'm sort of at a loss to explain it, wish it was more repeatable.

Thanks,

Ok, I looked into it and the user does not have a personal.xls file in the
xlstart folder of the computer and doesn't have rights to publish to that
directory.  So I don't think that's the issue.

Thanks,
