I currently have a shared workbook on a shared drive that several
people access to post their request for information. A few times an
hour, I check the worksheet and input a response. They later come back
and get the response I posted.

Problem: Various pc's keep locking the workbook up. The workbook will
say a certain user is in the workbook (although shared) and yet they
are not.

Any alternate suggestions?

Any way to create individual worksheet shortcuts on their desktops and
place the original in my workbook?

Or am I asking too much of Excel?
