Hmm, strange. I did setup a test here with two accounts at the same bank. No 
problem. The connection gets established twice and I see the second call to 
slotOfxConnected.  I wonder though, if the server plays a significant role 
here.

Can you run the above and trace the TCP traffic using wireshark or tcpdump? In 
case you know how to read the information using wireshark, I am interested if 
two connections are setup or only a single one. In case you don't, please feel 
free to send me the file you traced via private e-mail. It's all SSL encrypted 
and could only be read if we have the servers private key. I am pretty sure 
that it is in the interest of your bank to keep it private.

I am only interested in the flow of information to analyze what's going on 
here.
