Hi Ian, This works OK for me in the latest version of EasyEDA and Chrome or Firefox. Can you tell us what version of EasyEDA and browser you are using?

Hello and many thanks for the reply. Am using latest EasyEDA that i access via your web site, no idea how to find the version number. Browser is Version 64.0.3282.186 (Official Build) (64-bit). OS is Windows 10 Pro, latest updates. If you need more i am here most of time. BTW i really like EasyEDA :-) I noticed on one thread about a development for a local router. Well i have 40 years of C and three major projects that used networks/linked list models. Network management, Commercial Jet Route planning and World Best Puzzle Compiler :-) So if you need some help with local routing program, i will try to find time to help. Ian Knight

`Browser is Version 64.0.3282.186 (Official Build) (64-bit).` Is that Chrome? Could you share an example to illustrate this issue publicly or privately with Support? (See `Sharing` in the Tutorial)

Andy, Yes browser is chrome. I tried it again and same result. This is what i did after the copper pour had completed. 1. Pressed undo , result track's remove but copper pour still in place. 2. Pressed undo , components where moved back one by one. When last component was removed the copper area was cleared but the copper pour area boarder was still in place. Unfortunately the link to the how to share guide page is 404 https://easyeda.com/Doc/Tutorial/share.htm Ready for down time now see you on the other side. Happy to help Ian

Hello Andy, I just tested copper pour again on new system and is the same problem copper does not undo. However, if after the UNDO i do a page refresh in chrome the copper pour has been cleared. Ian
