I have a startup script that checks for valid IPs in a dataset and closes the application if "access is denied." I've got an error box via `system.gui.errorBox()` to alert the user, but I want this box to stay on the screen for a time (or until the user closes it) before exiting the application via `system.util.exit()`.

I've tried

```auto
from time import sleep

time.sleep(3)

```

between the errorBox and exit calls, but I always get a `global name "time" not defined error`

Is there another way I can do this?

Should this be tagged "Vision"?

Well, your script isn't working _right now_ because you're saying `from time import sleep` and then attempting to call `time.sleep`. If you want to call it as `time.sleep`, then just `import time`. If you're using `from time import sleep`, then you should just call it as `sleep(3)`.

That gets the sleep function working, but now my errorbox is blank as it sleeps

Yeah, because you're calling sleep on the event dispatch thread, which is going to disrupt all painting operations.

You need to use `system.util.invokeAsynchronous` to kick off a 'background' thread to do this waiting and closing operation.

Something like:

```auto
def waitAndExit():
    from time import sleep
    sleep(3)
    system.util.exit()

system.gui.errorBox("", "")
system.util.invokeAsynchronous(waitAndExit)

```

EDIT:  
`invokeLater` probably works too:

```auto
system.gui.errorBox("", "")
system.util.invokeLater(system.util.exit, 3000)

```

Perfect! Thanks
