[Suppressing the "Script is taking longer than expected" message]

Unfortunately, my problem with this is more than a mild annoyance, as my script is supposed to run overnight, and the message eventually crashes the script. Is there any workaround to this problem (even if it would take considerably longer to run)? What exactly does the timer count (it's obviously not counting time from the start of the script run)? Is it idle time, processor use?
Thank you for the speedy response!

Hello, I have the same timeout problem, with WASP 11 (version number 11.00.0232).
Was this ever fixed, as suggested by Duncan's post from 3 years ago?
Thank you!
