The startup page is the view you've got set up on the '/' page url on the perspective page configuration window. You can just modify that to the view you want.
Alternatively, this link will show examples on how to use the navigate function, but at the very minimum the Windows/Graphics/Overview you've put in there will require quotations around that string. Is that the folder structure you have under your views folder?
I will try all of these. Funny thing it was working yesterday, but i was doing quite a few updates.
Now this is what I get everytime I open a designer window.
