causes RoundCube to open a new window, and display the contents of the first email. What I was trying to do was highlight multiple messages for deletion.
Also when you highlight many emails and delete they do not show up in Trash!!!
OK sorry for posting here number one. Number two I think I figured it out once you send a draft it gets removed from Drafts automatically. Sometimes Drafts are nice when sending canned messages and you want to resend same thing many times.
Either dont auto delete on send or when you hit save draft leave the compose mode kinda confusind. Now auto draft save makes sence in this regard.
