Why would some PMs not be counted in "Unread" (RE System generated PMs)?

[Quarterbore]

I am trying to debug an issue with PMs that I have that are generated by the system. The issue is that when the system generates a PM the PM is not counted in the "Unread PM" count and users are not seeing them...

I have just did a test that caused a system generated PM and I manually sent a PM from the same account that the system had sent....

I found the PM table values were the same!

I found that in the PM text table there is a difference!!!

In the "To User Array for the system generated message:

a:1:{s:3:"bcc";a:1:{i:3;s:11:"Quarterbore";}}

In a PM that I sent using the site PM tool:

a:1:{s:2:"cc";a:1:{i:3;s:11:"Quarterbore";}}

Now, I went into phpadmin and changed the value for the "User Array" in the system generayed PM and it still does not show...

I welcome any advise as to where this infomarion could be saved or where it may be comming from so I can fix the script that is causing it...

Thanks!
