[AccessD] Folder 'Caching'

Hello to all!

I have a customer who, about a year ago placed my system under a networked
folder they call Secured.  It took me a year, but I finally was able to see
a pattern of errors where updates to my system were not 'seen' by the first
person who opened my system after an update, but they were seen by the
second person and subsequent people who opened it.  This has occurred where
I made on change on Saturday morning and the problem occurred on Monday
morning.

Today we also experienced an email automatically sent to a Supplier that had
the wrong due date on it!  But when we looked into the back end later, the
date was correct.

Last week I attended a meeting with some IT folks at this company, and one
of them said that he believed the folder was caching changes, but he didn't
know the details. 

This is the only place I've ever heard of this happening.  And I still don't
know what the folder is actually doing.

Has anyone come across this situation?  Do you know what that folder is
actually doing?  Or, is there anything I can do to work around it?

Thanks!
