No, I am not trying or using it. However, I reinstalled Lazarus, then I tried to reinstall RichMemo. It took several tries, but then I succeeded. Installing packages is not an intuitive process, and nobody (by what I have not found) has posted the rules.
Nevertheless, I am operating again. What stands is that "Size8, Size16, Size12, Strike, Italic, Bold, Underscore, and ColorRed" are being copied. Unfortunately, my RTF search box is also highlighting the import, and that is automatically turning all colors to the first color ... black. But nothing is highlighted (selected) with my RTF replace box, so it is keeping the color.
But superscript and subscript is being copied without the attributes ... and causing a crash. With this rebuild I am not even attempting to test them.
