I am using Windows 7 and Outlook 2007. Outlook mail and calendar work fine. When I click on Contacts however I get the message " Microsoft Outlook has stopped working, Windows is checking for a solution. After checking for a solution I get the message: " A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." This problem started a few days ago. Does anyone know how to solve this problem?
