# suspendStack

```
suspendStack
```

Handler:

```
on suspendStack
  [ph:statements]
end suspendStack
```

HyperCard sends the `suspendStack` message to the current card when the stack’s window becomes inactive (for example, when the user clicks another card window).

HyperCard sends `suspendStack` only when it is displaying more than one stack.

<b>Important</b>: HyperCard does not send `suspendStack` when the user switches to another layer under MultiFinder. (Click Related Topics for more information about the property `the suspended`.)
