[Anjuta-list] open a document

[ginzzer <ginzzer gmail com>]

I have anjuta 2.27.3.0 installed. I created a c++ project for test, I
can build the project without problem now. But when I click the [File]
tab, choose main.cc and click right-button of mouse, then choose open,
it suppose to be shown in the editor, right? But nothing shown! I don't
even see the editor. What's going on with this?
