I am wondering if this could be caused by McAfee which is sending an alert message, after a while, asking if we should allow this application to etc., etc., etc. Basically, I am assuming that after a while, if there is no answer, that it could cut the connection. This might then result in the connection was closed error message. Even if I click on Always Allow, this message will keep happening once in a while. Does anyone know how I can tell McAfee to stop verifying for that on that particular EXE?
