About OES Software Usage issues

[IAreCBTEF]

At present, in OES software(OES4.11.c), there may be writing errors during actual operations, but the software does not return to the previous operating status, although there are buttons for 'undo' and 'redo' in the software.Maybe there's a problem with my software, I don't know?

The undo button only works for smart forms (HMI views/dialogs), not for anything else inside OES/Control plus Studio.
