source file does not appear

[Blitzer]

When i start a new project I don't have a source file in the management window to the left, and nothing appears in the editor window.
however, when i run the project it prints: hello world!

where can i find my source file for the project. Is it running?

Have you tried to expand the tree under workspace?
If you have it will be good if you can post a screenshot (please use a image uploaded service instead of attachments!)
