Sage 100

Sage v2017 Premium. Has anyone ever seen or heard of UDF's disappearing from users screen anytime anyone accesses anything in customizer? We have a client that we cannot access UDF Maintenance, Scripts Maintenance, Customizer etc -at all- while users are in the system or all the UDF's added to screens (like Sales Order Entry) disappear until we run the Update Custom Panels Task. The other weird thing, is we CAN run the update panels tasks while users are in the system. So confused. I (of course) can't duplicate this, and Sage says you shouldn't be going into customizer while users are in the system anyway (which is a crock of you know what). This glitch has made its way through two upgrades as well. Started in 2013, then in 2015, and now in 2017. So it's being carried through. Thoughts??? TIA :)

I have seen UDF's disappear from some users' screens but never really determined what caused it. I just attributed it to general corruption.

That would explain why Sage just brushed it off. I am recommending we spin up a test server as we have lots of other things to test as well, so maybe I an see if it doesn't happen prior to copying over their data, then maybe it will after we migrate it in. Anyone have any ideas what files might be corrupted? We can copy them back in one-by-one until we fix it.

is this 100c?
