This happens to me in Microsoft Office Outlook 2003 SP1
Go to File > New > Mail Message
Press To... > Select a Contact from your Address Book
Press Advanced > Properties
Press Save and Close
- General, Details, Activites, Certificatins tabs will dissappear
- The Contact Windows will not close
Press Save and Close again
- Save and Close button will be disabled
- All the menus will be disabled
- The Contact window will freeze
Can you guys please try recreating the bug? I am not sure if this happens only to my system.
