I am running an Access 2013 application on a Windows 2008 R2 server. Some of the functions work perfectly and then stop working (Totals is the one that stops working first) on forms and tables. IT performs maintenance and updates of the software, either Microsoft Office or Windows 2008 and then the functions start working again.

I don't know exactly what is occurring, was wondering if anyone has experienced this and can give me some pointers to prevent this from happening.
