Hi Everyone,

A periodic automation annoyance visited again today and I'm wondering if
anyone else has experienced the same issue or already found a fix.

I check the automation queue every evening for obvious red flags before
leaving the lab. Sometimes ICON closes unexpectedly overnight, or so I surmise
the following the morning. I'm stumped on how that's happening. There aren't
any associated error messages that I've seen. This morning there was
notification for a MICS update, but iirc that has appeared before without
coinciding with ICON disappearing.

-Windows 10 TS 4.4.0
-Automatic windows updates are turned off
-Confirmed the computer did not power cycle
-Exiting TopSpin is disabled while ICON automation run is active (several
hours of experiments completed last night without issue)
-nmrsu is the only account with permissions to stop the run or exit ICON
(afaik students have not obtained my password)

I've tested the settings for robustness multiple times. If it's a user input
error then I'll confess that whatever they're doing exceeds my imagination.
The issue is infrequent, so I can roll with software crashes if that's the
underlying cause.

I'm all ears for hypotheses or suggestions of available clues I may have overlooked.

Kind regards,
Luke
