How to repeat:
create some tables in the model. open the EER Diagram. Drag the tables onto the canvas. Double click on a table to see the tab show up across the bottom. Close it. Click on a different table to see it's properties in the tab window below. Sometimes switching back and forth works. Sometimes it doesn't. I was having trouble seeing the properties of some of the tables. I was creating foreign keys and associating them to the other tables. Hope this helps.
