Message Notification is not working within text message window.


With the recent updates, I have noticed that the text message notification is not alerting that there is a new text message if the text message window is still open.  Is there any way to fix it or do i just need to use another program other than verizon messenger plus?  i can not continue to miss important, time sensitive message because this feature is not work.  Now i have to respond to the message, close the windown or close the app itself so I will be notified when a new message arrives.  It is very annoying to get doing this over and over for every message received.
