Sorry I'm unable to offer any constructive advice other than sack the one who
has it locked. I did have a similar problem some time ago. I think that
after a couple of days after unsharing the w/b it eventually got itself
together. I well remember the culprit so I will speak to him in the morning
for further info.

We are using an Excel workbook that has been shared rather "successfully";
however, now the file is "locked" by one user that does not even have the
file open. Further, on first blush, we are not able to delete the old file
to replace it with a "restored" newer version. Haven't tried DOS commands to
address it, but question is what is stored where to indicate that the file is
locked? Weirder yet, how can a shared workbook be locked?
