David, thank you so much for the followup and your efforts on our behalf. Yes, my firmware is v1.12. I updated it before my first use of the unit. Please note that I updated my original post. Although the 110 doesn't close in on Ground Zero as well as I had hoped because of the freezing/jumping, it still is a great little receiver! The 110 allows me to do paperless caching, a HUGE plus! It gets me close to the cache, battery life is excellent, it's easy to carry and fairly simple to use.
