In a Passmark script, how do you force it to skip the result dialog?

I'm running Passmark from a script in a batch of tests (BIT), but the rest of my tests never run because of the Passmark result dialog, so hanging at the end.

I've tried the suppresswarnings option, and the /i (ignore warnings) flag, no luck.
I'm probably missing something very obvious?

Any help appreciated, thanks.
