Running Firmware 2.01: Have had several instances of the Helix going into a lockout mode where no controls are accessible. Thought it might be localized to the Helix unit I had, so changed it out for a new one. For the most part the new unit has been functioning nominal, but I did have one instance of the screen lockout error occur in a weeks time (the other unit had about 12 instances in a week). The only way to get out of this is a reboot. I'm not sure yet what I might be doing to trigger this, but I can't believe I'm the only one that is seeing this problem but didn't have time to scroll all the post on this thread.
