Ths is Windows XP SP2, sorry. Meanwhile I was able to resolve the problem by setting Firefly to start when Windows starts. For some reason if I start it manually, it doesn’t like to restart once it quits. If I boot up with it on, then it seems to stop and start OK.
As for the log tab, when I was having the problem it said nothing. It didn’t add any entries when I hit the start server button.
