After applying security update MS12-060 you may experience problems with your Access database if you are using any of the Windows Common Controls associated with the MSCOMCTL.OCX file updated in the patch.  Problems may include hanging on opening an object that includes one of the controls, or error messages indicating that events have been cancelled.  Example error messages may include (but aren’t limited to) the following:

Error 459:  Object or class does not support the set of events. 

2501:   action cancelled

The expression you entered as the event property setting produced the following error:  Object of class does not support the set of events.

Security update MS12–060 may cause certain ActiveX controls to fail to load properly within pre-existing Access databases and when inserting controls in design view.
