Simple question- how do i really close a Connection? i'm creating a new ADODB.Connection object, opening it up.

then, i close it (cnn1.close), and i set it to nothing (set cnn1 = Nothing).

However, when i close my app, it's still showing up in the task manager as taking up memory... it randomly frees up memory after a while, but is there to a way to effectively close a connection?
