Program terminates after successful connection

[Ta Rik]

Hello,

If you could help me with my problem, I would appreciate it.

Here is my code snippet:

***

from py3270 import Emulator

myhost = "Y:L:ip:port" #Y and L to establish SSL tunnel and to avoid verifying host certificate

em = Emulator(visible=True)

em.connect(myhost)

***

In a blink of an eye, I am able to see a home page of my host (which means it connected successfully), but then the whole program terminates. It looks like a crash to me ?
Connection is good and working, since I have created one using wc3270 Session wizard and it works perfectly. But from python, it crashes.

Thank you.
