Nothing happens on create function

Question

I'm quite new to Oracle. After I've installed the database,repository and the designer, I tried to create an ERD via the Entity Diagrammer. I managed to create an entity diagram, but on adding new entities, through the 'Create Entity' nothing happens. I press ok and the created entity screen remains there. Pressing cancel removes the screen but also removes the entity.
Does anyone know what I'm ding wrong?
Thanks

1. you have to have an applicaion created.
In the Repository Object Navigator - Right click Global Shared Workarea - Crete Child - Select Application Systems - Enter a name and then save
2. from the front panel select the Entity Relationship Diagrammer (ERD)
3. Select New Diagram
to the right of the drop down is a table page select your application( it will be in the drop down from now on) - OK
The gray area now had a new working area named ERD1
4. You should have a new tool bar at the top with an arrow and the oblong that says Entity when you run your mouse over it.
5. Click the Entity icon once and go down and click your workingarea. You should have a Create Enity box and a selected dashed box of where the entity is going to be.
Enter the Name and OK.
The Dashed box is now a solid line box with the name you selected in it.
Double click the box and now you can populate attributes and all the other options you will need.
