If you do this, make sure you keep plenty of backups.

If the last change I made deleted 42 important worksheets and I was going to
close without saving and 90 minutes later your code saved that workbook, someone
may have more work to do.

Hello
I am having a problem with a file being left open and I would like code to
automatically close the file after 90 minutes after the last change on any
page in the wb with changes saved before the close.
Can this be done? How?
Thanks
