Bug report hog 4.0 fm - system freezing but not crashing and keystroke @ - value doesn’t work

I’m running 4.0 on an HPU with a nano connected to it. It will randomly freeze but doesn’t fully crash. If I press pig, open, backspace it will unfreeze. 

Also the keystroke fixture @-10 does not work unless I touch or suck the fixture first. Fixture @+value works fine without having to touch or suck values into programmer first.
