Tips
- You cannot open a project exclusively if it is already opened exclusively by another user.
 - Opening one or more projects exclusively closes all other projects that are open in your view that are not already opened exclusively by you.
 - The locked project icon indicates a project is opened exclusively. Click on the project name to show which user has the project opened exclusively.
 - You cannot open a project exclusively if another user currently has it open. You are prompted with a message that includes the name of the project and the user. You can send an email directly from the dialog box requesting that the user close the project.
 - You can see which users have a project open by selecting the project and clicking Users in the Open Projects dialog box.
 - All projects open in your view are either opened exclusively or opened in shared mode. You cannot open projects in exclusive mode and shared mode at the same time.
