Hi, I have an issue with 8.8 general version. If you open an email and try to copy a "HTML" document with colored letters it will copy in black only colors.
I can not reproduce this in The Bat! 8.8.2 32bit on Windows 10 x64.
I sent a HTML mail containing colored chars by Thunderbird, i opened the mail in The Bat!, i could copy from HTML tab the colored chars and paste them in new mail editor (selected HTML format in editor).
May be you did not use The Bat! editor in HTML mode?
