That's the weird thing, I've now had this happen to me across two different computers, multiple times. At some point I'll notice that farr is no longer running, try and restart it and realize it's not starting. Go delete that section in the ini, and it works just fine again.
I've got some of the crash dumps if that helps. I've been using farr for a decade now, but this is the first time I've been switching between monitors so frequently.
I guess I'll try putting back in that section next time it crashes, or let me try and figure out some sort of watchdog script so I get notified when farr crashes.
