After enabling customize under Configure in the Preference’s palette, I docked the UNDO and REDO buttons from the EDIT palette just above the canvas window. Unfortunately neither buttons ever light up and hence become useless. I’m wondering if there could be a bug or is it something I’ve failed to correct. It becomes an annoyance when I always have to revert to the history palette as opposed to the quicker, more accessible UNDO and REDO buttons. Thanks in advance for your help.
