"Open Entity Modeler in a new window" was selected in my setup, and to check up a reported issue on Jira, I unchecked that option. Alas, now Entity Modeler open in the main window with my model, but a blank Entity Modeler window is also opened.
The other issue is a bit similar. If you check "Open Entity Modeler in a new window" and you close Eclipse while having a Entity Modeler opened, when you start back Eclipse, the Entity Modeler window with the model will open, that's fine, but a blank Entity Modeler window will also open.
