Not if you left netscape running on your console when you left your
computer, and you're logged in remotely to use mutt. I do this every
day.... The safest check is to talk X. You can might be able to
find standard shell tools (xlsatoms, xlsclients, etc.) that return
well-defined exit statuses under known conditions on all platforms, but
I wouldn't count on it.
Since I'm not sure this is in the archive enough times, I'll include a
one here. :) It's more friendly than is necessary.
