I finally decided to take a chance and update KK from 2.9.6 to 3.1.0 (due to ability to resize). I noticed on first launch that Windows thru me a firewall popup asking if I wanted to Allow ScanApp 3... I answered Allow but without really knowing why I needed to grant this permission. I certainly don't want to allow permissions if this means in any way that the KK startup will slow down because it's going online to fetch some authorizations (or whatever it needs to do.)
Can someone chime in and let me know if it's necessary to Allow this, and why? What happens if we don't select Allow?
