I guess, to be more clear, my issue comes when I want to go from, say, pattern 1 to pattern 2, and up, or then back down. I think Chris' initial links kind of address that.
I'm pretty good when staying in one pattern or another across the strings, but when I want to smoothly move into the next (or previous pattern) up or down the neck, I guess I'm having a mental block and losing where I am on the fretboard and remembering what the next pattern looks like as I try to move up or down the neck.
