If you have opened several projects in the Work pane,
one tab displays for each object that you have opened. Lots of open
tabs can make it difficult to find the projects that you are actively
working on. You can close old projects that you no longer need in
the Work pane.
Procedure
In the Work pane, click the X in
the project tab that you want to close. Closing a project
removes the tab in the Work pane.
If
you close a project, you can open it again by using Show or
by clicking
in the Work pane
toolbar, typing the project name, and clicking OK.
If
you do not remember the name, you can query first, then follow the
instructions in Showing properties in the Work pane.
