It runs fine on my PC with sub-classed winsock under VFP9.
Try to make oFwsock a property of the Pop3EmailClass class

* Init
This.ofwsock = CreateObject('fwsock')
This.oSocket = This.oFwsock.sock.object
...

* Destroy
This.oSocket = NULL
This.ofwsock = NULL

>i don't have anything on it just the olecontrol attaching the winsock activex.
