Hello It means you call directly ecREDO from Editor commands? This is a new information. I will check it.
aREDO and aUNDO are disabled when there is no item in stack. Editor commands call directly editor component. I must check how is it done there. -- <https://forum.pspad.com/read.php?6,76011,76075> PSPad freeware editor https://www.pspad.com
