I'm using version 6.1.37 EasyEDA software, not the browser. Theme settings "Creating new schematic" and "opening new schematic" are checked. Problem: When change schematic sheet (border) color, after save the file, when close and reopen it, the sheet color returns to its default. This happens also if I save my preferences to the server and reload them. Situations: 1- Change schematic sheet (border) color in theme settings. After saving file, close and reopen it, sheet color returns to its default (#880000). 2- Change sheet color at the right side panel attributes. After saving file, close and reopen it, sheet color returns to its default (#880000). 3- Change sheet color at the right side panel attributes or theme settings. After export file in EasyEDA format, close and reopen the exported file, sheet color also turns to its default (#880000). After discuss this issue at Schematic category forum, named as "Sheet color (border, not background) is not saving", I decided to report this as a bug. Thanks in advance, Miguel Garcia
