Hi fullmetalcoder,
Regarding the opening projects issue, I was using project->open, since file->open->project simply opened the file as a text edit, not as a project. But this is what I would expect.

1.So I create a new project using project->create new project,
2. fill in the details and click ok.
3. the project file is created and the file is displayed in the the window.
4. All the add files, sources, create file, basically all the project options are disabled.
5. So I close the file, and go to project->open project.
6. Find my testproject.pro, click open and nothing happens. The same with any other .pro file. Nothing.

Hope this helps.

Thanks,
Phil Winder
