The update also addresses a suite-wide issue that caused increased use of computer resources when dragging a file or object over an Office application window.
Each of the applications in the suite have received several improvements. One of the problems solved in Excel is the one concerning a bug that caused the unexpected opening of workbooks or other files when the application was opened. Unexpected PowerPoint exits have also been fixed, as well as unresponsiveness in Entourage for several minutes.
The update is available through the Automatic Update feature in Office.
