I have this little bit of code at the end of a sub to save the name of an
open Excel workbook:

oxlWks.Application.DisplayAlerts = False

oxlWks.Application.ActiveWorkbook.SaveAs filename:=fname,
FileFormat:=xlNormal

oxlWks.Application.DisplayAlerts = True

I have run this hundreds of times before without a problem, yet today it was
bombing out on me. I had made a small change to the sub, so I opened a
prior version without the change and still had the problem. I get a message
saying "The server threw an exception". This is happening more times than
not, but not always. The sub creates a workbook of the same name earlier in
the code, so when it works vs. when it does not work always involves saving
over an existing workbook of the same name.

I do seem to be having memory leaks, Excel will not shut down properly.
That may be related to the problem after it occurs, but it may be unrelated
to the cause, I really do not know. I went to the directory where all of
these workbooks were being saved, deleted them and then the system ran fine
again with no problems at all - I ran the same customer over and over so it
would be sure to overwrite the file and it did so easily. While this now
seems to work, I am concerned about a recurrence of this.

Any ideas about what could be causing this? Is it time to get incense and
sacrifice a chicken?
