@Tomato You could always take this as an opportunity to make the UI more obvious as to what needs to be done.
Perhaps you could change the button to say "Select a message to send", then when the user has selected a message, change the button to say "Send", and enable it?
You could also reduce the clutter by removing all those "Select" buttons, and making each message a button in its own right. Make them all a light blue with rounded corners, and make the selected one that blue colour so it's obvious (and then enable the "Send" button, as above).
Just a thought.
