CP_OnSelection = {Yes|No}
Indicates that selecting a project automatically switches to it:
CP_OnSelection = Yes
If this variable is set to Yes, every time you select a project in VSS Explorer (either with the keyboard arrows or with a mouse click) it becomes your current project. If the variable is set to No, you must press enter (or double-click with the mouse) to make a project your current project.
You can also set this variable in your SS.INI file by using the Make Selected Project the Current Project option on the View tab in the SourceSafe Options dialog box.
