UPDATE: A completely different glitch occured on the 7:58 PM LF; this one was even stranger than the 7:28 PM error. The LF worked properly for about 2 or 3 seconds, and then the area on top of the LDL turned black, and then turned gray. A national map (seen on 1-minute LFs) then appeared, and the LDL froze at the same time. About a half second later, Trammell cut in - and it stayed on the Trammell feed for the rest of the LF. I wonder what the hell is going on with the HD LF.
