Would be interesting that you publish the call stack at the time when you cann connect after the close.

I do not call Connect from the Close event but, the events that cause data to be requested are asynchronous and a request could occur almost immediately after a Close. So, I am wondering of I should be concerned that my TTnCnx object is still in the process of handling a call to Close when I issue a call to Connect. Another thought, could my problems be related to the fact that, when a Windows socket is "closed" it does not close immediately but hangs around for a while (I say this based on watching Netstat results). Any other thoughts on how a TTnCnx connection might stay up even though Close has been called?
