[Twisted-Python] question about twisted conch (SSH) and wxPython

[Astan Chee]

Thanks for that, but since I've been using twisted's ssh, it doesnt 
disconnect me from the server whenever I exit. It seems that for some 
reason if I call the SimpleTransport class after I've called and 
destroyed(how do I destroy a protocol.ClientFactory() class anyway?)  it 
once, it becomes stuck. I wonder if this is an unresolved bug, oh well. 
The logs look something like this:
