N 6.0.7 64 bit crashing on exit

I just installed 3.1.3 (up from 3.1.2) and I tried your “remove from surfaces” idea. The good news is that N6.0.6 did not crash on exit. The bad news is that Eucon was still ABSENT when I restarted a second session. Nuendo didn’t see the MC and vice versa. I’m on a PC, does that matter?

Also, my tracks screen DOES NOT UPDATE when I go beyond the listed tracks. I read a post that said the screen did update when using Eucon Ver. 2.7.1. Is that correct? would I be able to restore that function IF I were running this iteration, or will it not work with N6 at all?
