I\'m running vim 7.3 on a Mac 10.7.2 and I\'m having some trouble cutting and pasting several lines.
On my old Linux setup (which was stolen so I don\'t know versions)
Not sure if this is close enough to what you're trying, but one thing you could do is use a specific register, and capitalize your register name. That tells vim to append to the register rather than replace it, so if you have the lines:
one
two
three
you can enter
"qdd
"Qdd
"Qdd
and then subsequently if you enter
"qp
it will paste back the original lines
