You can enable a confirmation dialog box for when you delete a window from a workspace that asks if you want to permanently delete the window. By default, this setting is not enabled, therefore unless you enable the setting, you will not receive a confirmation message before you delete a window from a workspace.
A check mark in the Confirmations check box indicates that a confirmation message will appear when deleting any window type. A green square displayed in the check box indicates that, for one or more windows, the delete confirmation message was displayed and you selected the 'Do not display this message again for this type of window' option. Thus, the confirmation will be displayed for some windows, but not for others. To reset the display of the confirmation message, you can either clear the check box (disabling the confirmation for all window types) or re-check the check box (enabling the confirmation for all window types).
