Version: unspecified (using Devel) OS: Linux If you try to send a mail without recipients an error message appears that tells you no recipients have been entered. You can only click ok to this message and then it only disappears. I would expect the email tab showing up when the message is closed so one could immediately enter the recipients. I guess if you are on a bus and everything shakes it's much easier to just click send, close the message and enter the recipient then trying to switch out the recipient tab first. Reproducible: Always
