I would try going to Save as instead of Save when saving the form file and see if that helps with the issue.
If that does not help, I would create a support case with our support team with those steps to reproduce the issue - the PreForm log file can potentially help too.
Thank you for sharing your experience. I did try to recreate the issue on my end on my laptop and could not, so bringing this to the support team’s attention with the log files and as much information as possible (my gut is to see if you have a removable/separate network drive that PreForm might be trying to use after waking up) will help us figure out what is going on.
Definitely feel free to update us here, as I am personally curious myself, and it’ll definitely help those people that only browse the forums.
