# Syntax
set the destroyWindow of stack to {true | false}
# Examples
set the destroyWindow of stack "Test Harness" to true
# Description
Use the destroyWindow property when installing new externals, or to save memory.
If a stack's destroyWindow property is set to true, closing the stack removes the data structure maintaining that window.
External commands and external functions are removed from memory only when the stack controlling them is removed from memory. When you install a new external, or replace it with a new version while debugging, LiveCode cannot use it until you either quit LiveCode and then reopen the stack, or close the stack (after setting its destroyWindow to true) and then reopen it.
>*Note:* Despite its alarming name, the destroyWindow property does > not destroy or damage a stack. It simply frees the memory used for > its window.
