Hi, I think my Thunderbird may have updated. (87.0b1 (32-bit) Its been fine for years but suddenly I can no longer attach emails onto an email by dragging selected mail from my inbox onto my email that im creating. I can also no longer copy attachments from specific emails in my inbox directly onto a new email either. I used to just be able to drag and drop. Now im having to save each individual file / .eml i need to attach to a new mail im sending and then click attach or drag and drop for File Explorer. Has something happened with an update and is there any way I can enable this back on ? Thanks
