We use a form procedure to handle the situation you describe. Although this won't truely capture your "message" statements, it can be used in place of them.

• start procedure code -----------

Procedure Put_Message (Msg_Txt IN Char) Is

-- 
-- Moves messages into pop up alert
--
-- Alert "MESSAGE_ALERT" must be defined
--
-- Use Put_Message('message text') instead of MESSAGE('message text')
-- Use in ON-MESSAGE Trigger
-- 
Alert_Id Number;
--
Begin
  Change_Alert_Message('Message_Alert',Msg_txt);
  Alert_Id := Show_Alert('Message_Alert');
End;

--------  stop procedure code -------------------

To make this a little more generic (but also more cumbersome to call) you 
could not hard code the defined alert "MESSAGE_ALERT", but pass it in as a 
parameter.   

This procedure has become a standard at our site, so we use 
PUT_MESSAGE and MESSAGE_ALERT exclusively over MESSAGE on the status line.

Hope this helps !
