After installing the Private Message Center and a few other hacks some of my members are noticing that after they reply to a Private Message, the original message that was sent to them has been deleted and/or removed? Why is this? I am trying to figure out what I can do to stop this as the users should not have to lose their messages as you are supposed to be able to store up to 60 msgs.

Everyone's thoughts on this to help resolve this issue are most appreciated.

That always happens, It's not the hacks fault.
