How to cancel IB TWS Automatic exit feature

Hello,
I want to cancel automatic exit of TWS software from Interactive Brokers. I am not able to find how to set it in TWS options. Can somebody help me ?

 

I don't think you can, but there is software to make it automatically re-login

 

You can get IBController from the TWSAPI group at Yahoo Groups (http://groups.yahoo.com/). This software will keep TWS running for however long you specify in the code.
