B4J Question Project folder not set

Have you given the project a name and tried to save it under File/Save? I have seen the "Project folder not set" if you try to compile and have not save the project.

When you start a new project, the IDE doesn't know where to put it, so you must perform a save operation indicating where the project files will be saved, after that, with each new compile action, a save is automatically performed by the IDE in the project original folder.

Thank you for the answers.

When i try to save nothing happens.
If I use a already saved project, like the examples everything works fine.
