sIs it possible to set the length of time you can keep a workbook open
for?
I have several people updating a single file and oftentimes they leave it
open on their desktop - thereby preventing others from updating it. I
would
like to set the amount of time a file can be open for so that other's can
access it.

Any ideas?

Thanks.
