[SOLVED] new projects disappear from Project List

Hello all,

When I create a new project and save it : I can see that project in the Project List. But as soon as I want to change the field "is sub project of" to nothing, it disappear from the Project List and I can't acces to that project anymore even with its id !
If I set that project as a sub project of another existing project, I can see it in the list and continue working with it.

What's wrong ? Why does the project disappear ?

Yes, that's it, the project selector on the top left corner of the screen !
It was limitting project list to one projet and of course its sub-project only.

thank's
