Selectable recipient works, but no success message showing up

Hi,

i’ve a form with an selectable recipient. That part look like tha:
[select your-recipient "AAAAA|[email protected], [email protected]" "BBBB|[email protected], [email protected]"]
In the “To:” field i’ve added [your-recipient] and it works, i can select who gets the mail if someone is pressing the send button. Mails are send and so on.
Problem: If i use these selectable recipient solution, no success message is showing up, after successfull sending the mails. So people press the button 5 times and i get 5 mails, cause they don’t know that it was working.

Switched to an fixed recipient fixed this, but i need the selectable recipent.

Looks like a bug, right? ??

Thanks for this great plugin!
