What Does It Mean When I Get the Message "Dialog Box Is Open"?

The "dialog box is open" error message is used in Microsoft applications and its implications depends on the program it appears in. It may appear in Outlook webmail or in Microsoft Word 2003 or 2007. In Outlook, it may appear if the user has not completed the user information data for their version of Microsoft Office. In Microsoft Word, it can be an indication that the Officeav.dll file - which is the Norton-Antivirus Word plugin - is outdated or corrupted.
