    I don't know the reason for the issue, but I too have had many problems
    with screen. (4.8 or 4.9 box?) It works, it just uses up all the CPU
    available. (Starting at 0.x percent going up to 100 percent) The fix was
    to build the screen port, and the problem(s) went away.

    I don't remember specifically on which releases this issue occurs, I do
    know that it's been more than just a single one. I've had the same issue
    on several different systems as well.

    Just build screen from ports and the issue will go away. I haven't
    (directly) used python before, but it's always been built from ports as a
    dependency of another port. That might have something to do with it.
