Just to put this in context, the only reason I'm even trying to do this is because wog pointed out on my last question that it's possible to start a child process *before* you start up MainWindow in a perl/tk app and not have the child process calls to POSIX::exit get screwy. What I really wanted was to just use fork and have the children exit when they were done getting a URL, but even if I call POSIX::exit it still trys to call TK::exit! arrrrghhh!!!

Anyway, thanks again for trying to help. I'll just have to keep at it. Your comment about just letting it block seems to work, but there is something strange about that too. I'll investigate and post later when I know more.
