I am receive the message "This page contains both secure and nonsecure items." when browsing some messages from mobile interface using IE6.
It doesn't occur using Firefox or IE 8. I used the full browsers to troubleshoot because I could not browse the messages from a mobile device.
I have tried WM6 and two BB 8820 's. The mobiles do not display an error message, but the email isn't fully displayed. Only From, to and subject is displayed.
