Beginner needs help

When I first opened the Interface builder I closed several windows, just experimenting with the thing, now I cant get the windows open for the Library, Main IU, etc. What's the secret to getting these windows?

Another question, I stared several projects in cocoa that I want to delete, how do I delete old projects?

Thanks,
Bob

Yes, its strange that they have 2 places to look. For the Main Document objects you need "Window > Document (command - 0 (zero))" Menu and the other pallets are found at the top of the "Tools" Menu.

You just locate the Folder with the project name and Trash the whole folder. There are lots of additional Files and Folders that make up a Project so just deleting the .xcodeproj file would have little effect.
