IRIS - Periodic Forced Refresh in Management Console
I'm not sure what the purpose of this is, but the Management Console causes the browser to refresh periodically. If you're in a form or an editor such as the DTL or Routing Rule editors, you may lose work unless you save frequently. This did not occur in Caché 2018 and earlier releases.
I've had a couple of incidents where I've created a number of rules in the DTL editor, answered the phone or stepped away for a few minutes, then come back to find any work since the last save erased.
I've noticed this in both 2019 and 2020 releases of IRIS.
