the only time i've ever seen open break is when the connection is over
ssh--contrary to (perhaps naive) expectation, ssh'ing into a mac and
running, say, "open ." doesn't open a new window in the remote box's
local Finder, it just fails. (or at least it did under panther, which
is the last time i checked.) i don't know a whole lot about how open
works, except that it seems to be a carryover from NeXT, so presumably
it's all about NS classes and cocoa frameworks.

i guess the question is how open gets its connection to the local apps
it sends messages to, and whether that could be disrupted by the sort
of pty-fiddling screen does.

anyway, just some more wild speculation on my part. enough rambling
for now. good luck.
