Hi Shay...
Ok well... if i'm understanding you right Shay the first error message is simply saying that "you cannot move an individual channel. Only the master RGB channel." -- which actually means 'the whole image'.
And the second one is just what it appears to be -- a new channel where Photoshop will store all of the data from the Adjustment layer. Don't be concerned about it though. It's doing no harm, and you'll only ever see that channel when you're on that specific layer.
Hope i got these correct.

Anyone else care to edd to this? Fire away!
