Well, after your last comment, I only change the theme of Ubuntu with a custom I used before (only icon theme) and indeed the issue with the program has vanished and the drag-n-drop works again. I would not have imagined that such a change could have such consequences. It had never occurred to me in the past.
After the change of the theme, it now works again with all themes, including the default of Ubuntu! I assume you are working to make clear what causes such conflicts and thank you for your interest! -- [Gutsy] Drag-n-drop function does not work for moving/ copying messages between folders https://bugs.launchpad.net/bugs/147751 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
