Locking Windows Open

Locking a window helps prevent you from accidentally closing a window that you want open.  If you try to close a locked window, a dialog will prompt you to confirm your intent, and will give you the option of removing the lock. The Log window, for example, is locked by default, because it displays messages about the IDE, which you would not see if the Log window was closed.

To lock a window open, select Lock Window from the Window menu; a checkmark will appear beside the menu item. 

To unlock a window, select Lock Window again; the checkmark will be removed, and you can then close the window without receiving a warning.
