The fact that the remote returns to normal by restarting with the card out suggests the issue could be with the card (they are purchased in bulk, it is not out of the realm of possibility).
I have two extra Lexar cards around, I've tried these and it makes no difference. Highly unlikely that all three cards are bad. It is almost like there is some sort of issue with the card interface itself. Most of the problems with my first CC revolved around the condition of a card being in or out, just as some of the odd behavior with the new CC. The new CC also refused to change the Einstein's modeling light status, along with the odd WS numbers on the AB400.
The fiddling I did seemed to solve the problems for now. Currently running with the SD card that came with the new CC.
There's a gremlin in there somewere...
