database properties is missing???

[chaoy]

I created a data model using visio 2003.
After I got a error message which I forgot it, I can not read database
properties. I was used to click a entity(table), and could read its
properties such as definition, columns, and etc in database
properties. After the error, the database properties window just show
"informamtion" instead of the properties of the entity.

Thanks a lot in advance.
