Users with more than one session can experience a problem where an inactive session times out (TSO timeout) and whatever messages the inactive session sends will interrupt the active user's session. 
For example, a user logs into TSOA and into TSOB. User continues to work in the TSOB session. Eventually the TSOA session reaches the SMF timeout and is cancelled. The cancel messages and termination messages are thrown onto the user's screen even if they are in the middle of typing. Then the screen goes back to the TPX menu, but not to the TSOB session.


The Output Option in the TSO application session was set to SWITCH.
This value was brought over during the Teleview migration to TPX. 




Remove SWITCH from the Output Option: ________ which is located on the second panel of the application session in either the profile or user maintenance panel.
See panel example below:
From the User Maintenance Panel in the Session Options:

ALARM -means that you wish for the terminal to sound an alarm when output arrives to this session.
