I use a color palette with about 200 colors, including tints and shades, all carefully organized in a fixed order for easy access. I recently upgraded to XDP X11. Like it's predecessors, it defaults to deleting unused colors in Utilities > Options > View. When I opened a large pre-existing project file with hundreds of diagrams on multiple pages, it deleted from the color bar all the unused colors. It took me two hours to re-insert the full palette from my starter file and then move the colors in the color gallery back to their proper positions. I thought this would be a one-time annoyance, but I just reopened the file and it's happened again.

Has this happened to anyone else? Is this a bug? Is there a way to lock the palette and color bar so this doesn't happen again? (I have already unchecked "Delete unused colors and styles when saving" -- my most hated feature in Xara as I see no benefit to it!
