Uncheck this box to remove the OS/2 default "Sort" submenu from the desktop's context menu.

Note that as opposed to the corresponding setting in the "Workplace Shell" object, this will remove this item from the desktop's context menu only. On the other hand side, the setting in "Workplace Shell" has no effect on the desktop. This feature has been added with V0.9.0 because several people asked for it to protect themselves from messing up the desktop accidentally.
