Titlebardll.dll error when closing Access database

Hello.
I have a user who gets an error every time closing out of an Access database application. It occurs with any Access database that is open, not just with some of them. The error is on the file titlebardll.dll. Access closes out with the error and attempts to restart, There are also occasionally memory address reference errors that precede this error. Is this just a case of bad memory? It doesn't affect other applications, just Access database applications.

Thank you for any help.
