This is isn't a problem, just a screen that I don't know what it is for sure. If you're in the TP list on the MicroHD and press the mute button, it comes up. Curious as to what it is.
I'm sure Brian (Titanium) can tell you what it is. I think he explained those hidden screens right after he had the MicroHD developed, and there is a posting around here that gives to magic keystrokes to get to them.
