Actually, you have a bit of mixed metaphor here - "free viewing" involves
holding your eyes parallel as if you are looking at someting at a great
distance (or maybe even with your eyes slightly DIvergent). "Cross-eyed"
viewing involves having each eye CONvergent, but still focussing at
a distance. 

I find in my case that I'm more limited in the
"free-view" mode than the cross-eyed mode. I can converge most anything
cross eyed, but have definite limitations in diverging more that 
"looking at infinity". In both cases, what some people have difficulty
with is being able to focus at a different distance than they are
used to doing (ie, in cross-eyed focusing at a distance, and in
"free-viewing" to focus close in). Another effect some people have
is that "free-viewing" tends to make pictures appear enlarged a bit
while "cross-eyed" tends to make them look smaller. I don't know if
we ever decided whether this is a "real" effect or psychological.
