More Nano HogPC bugs?

Not sure if anyone has experienced this (or if it was just a one time thing, CPU issue, etc)...
Last night while I was programming, my Pig key stopped working. After a few hours of work, all Pig+ functions just stopped. I did the most obvious fix, restart my show (did not power down CPU or Nano) and the problem went away. I will be keeping an eye on this and I will report back.
Has anyone else experienced this? Or am I missing something (ie: a way to disable or enable the Hog key functions)?

Cheers!
Eric
